Do It Yourself Marijuana
Since this a beginners’ guide to growing marijuana, we’ll start with some basics about the plant itself.
About the plant
There are two main strains of cannabis: Cannabis Sativa and Cannabis Indica.
Both are basically hemp plants.
Industrially grown hemp, Cannabis Ruderalis, is a strain of Sativa. While great for rope and other fibers, industrial hemp is no good for smoking—it’s been bred with a much higher ratio of CBD (cannabidiol) which cancels out the THC (the psycho-active chemical in cannabis). Hemp seeds and oil from these plants do have numerous health benefits though. Also, experienced growers will sometimes grow Ruderalis to breed with other strains to create new hybrid varieties.
So when it comes to Sativa, it’s the marijuana type you might be looking to grow.
However, Sativa strains are easiest to grow outdoors. Which brings us to Indica…
Cannabis Indica is closely related to Cannabis Sativa but has a relatively higher ratio of CBD to THC, which makes it the more frequent choice for medical use.
In terms of effects, think more of a “body buzz” or a stoned feeling, rather than Sativa’s more uplifting, creative high.
Indica strains also produce a shorter, denser, quicker growing plant which is what makes it ideal for indoor growing.
Whichever strain you grow, usually the leaves and flowers are dried, crushed and then smoked with a pipe or in cigarette form—although there are plenty of other ways to prepare and ingest it if you’re not a smoker.
For the ultra-newbies among you, the plant goes by many names, the most common being:
What the plant does to the smoker, and how effectively, depends on the quality (and variety) of marijuana, which in turn is dependent on the quality of the plant growth. In different regions, for instance, due to different weather conditions, growing methods and techniques, each type of plant can have its own individual taste, aroma and potency.This guide doesn’t cover the topic of hybrids, but as you advance in marijuana growing you’ll also learn that there are all kinds of different hybrid strains to experiment with—you might even experiment with creating your own.
Growing marijuana can be fun if you are fully aware of what you need to do.
And if it’s legal where you are, and you find you’ve got a talent for it, you could even start up your own business and become a weed entrepreneur.
This post tries to focus on the most cost-effective methods to get started.
How to Grow Weed–the Basic Stuff
The main factors to consider when you grow weed are:
Understanding, controlling, and balancing the above environmental factors is the key to a successful grow.
But don’t worry if you have no idea about all this yet! That’s what this guide is for.
If you follow all the steps, you should be well on the way to your first successful indoor cannabis crop.
But first, a little more about how marijuana is consumed…
(Want to skip straight to how to grow weed indoors? Just click here.)
Effects of Marijuana–Cannabinoids
What causes the different effects of weed?
In a word: cannabinoids. This family of chemicals is produced by each strain of cannabis plant in different combinations and concentrations.
They’re what gets you high after smoking weed. The level and potency and exact effects on your mind and body depend on the quality and variety of cannabis and the way it is grown, prepared for use, and stored.
Tetrahydrocannabinol (THC) is the key active ingredient. Although this type of cannabinoid is present in all parts of the plants (male and female plants), the resinous tips of female flowers (cannabin) are especially rich with it.
By using these THC-rich parts of the plant, a much stronger drug is prepared with the name hashish which is generally perceived as being eight times stronger than marijuana.
Is Weed Good or Bad?
Effects can vary from person to person and depending on exactly what’s being smoked. But it’s generally agreed that cannabis can have the following positive effects:
- Stress relief
- Mood changes
Some People Report Improved Thinking or Sensations
- Better ideas and more positive thoughts
- Pain relief
- Nausea relief
- Heightened levels of pleasure toward everything (music, sex, laughter, etc.)
- Heightened senses
Negative Impacts of Marijuana:
Everything when used in excess has a bad effect, especially when it comes to euphoric drugs. These negative effects can include:
- Short term memory loss
- Respiratory disorders (cough, asthma, etc.)—especially if smoked with tobacco
- Psychologically negative impacts
Ways to Use Marijuana
Now you’ve got a rough idea of how weed works, let’s look at the more popular ways to consume it:
Burning weed to release the THC and absorbing the smoke in the lungs is the most popular way to get high. Health gurus suggest that users should take light puffs, as these cause less stress on the lungs. Remember also that too much smoking can cause asthma. And we all know about the health risks of tobacco.
Special pipes exist to make marijuana smoke cooler (we mean the temperature—but some pipes can look pretty cool too!). Although some experts say that this is not the safest way to ingest, many smokers favor a good pipe—look for pipes made from stainless steel, glass or aluminum, to ensure a cleaner hit. Try to avoid wooden or plastic-made pipes and bongs and their potential extra carcinogens.
Smoking Joints, Spliffs, or Blunts
This might be the least healthy way to consume weed, especially when the joint includes tobacco (technically that makes it a spliff rather than a joint), yet it’s also probably the most common.
Fat joint vs. thin joint is a never-ending debate, but eventually, it all tends to come down to a matter of preference.
Whether fat or thin, however, the key thing is for the joint to be tightly rolled. Tight joints burn more slowly for a smoother smoke.
Spliffs give a lower-level high because there’s less weed in there, but the THC high is mixed with the added nicotine buzz.
You’ll also see joints rolled with a tobacco leaf skin, cigar style—more so in American than Europe. These are known as blunts.
Water Pipes and Bongs
Bongs and water pipes tend to be considered a more efficient, cleaner smoke than a joint.
Why? Because there’s no tobacco involved, no paper to adulterate the taste, it’s not constantly burning, and the water and percs or filters cool and filter the smoke for easier inhalation.
However, you’ll still find some people who claim smoking marijuana through a water pipe literally sucks.
Even though THC isn’t water-soluble, it’s sometimes claimed that some THC gets filtered out through this method—possibly because it gets overly cooled, possibly because the smoke passes through a lot of filters/percs.
Either way, it’s another method to add to your “tasted and tried” list. And it might well be the one that works for you!
Inhaling or Vaping
Inhaling or vaporizing is a process in which the cannabis is heated up and the vapor of the weed is inhaled by the consumer. It is one of the cheaper, more efficient ways of getting high on cannabis as you can create your own vaporizer or inhaler at home. It’s also one of the mellower ways. Ideal for those who don’t otherwise smoke.
Used as an Ingredient
Some people eat cannabis raw, which may or may not get you high (there are plenty who say it works for them and plenty of others who say that that doesn’t make any sense scientifically).
But using it as an ingredient is pretty popular and definitely works—but be careful you don’t accidentally take double the dose assuming the first brownie or mug of tea was a dud!
The effects can be a bit delayed when eaten… but they will kick in. Maybe an hour later, sometimes even as much as 3 to 4.
This is also a pretty economical way to get high on marijuana. And can be less unhealthy as well—depending on what food you like to add it to, of course!
Other Uses of Cannabis
Apart from smoking, inhaling, eating, or drinking, marijuana is used in a whole host of other ways as well. The following list of products testifies to its versatility:
- Topical pain-killing creams and lotions
- Cannabis oil (here’s how to make your own)
- Health and beauty products
- Massage oils
- Used in some medicine
As you can see, marijuana doesn’t have to be used on its own, or just for getting high, it can be beneficial as well in combination with many other chemicals and natural herbs.
There’s a LOT of debate amongst stoners and other marijuana users about what’s the best way to use and consume marijuana, but really it’s all about finding the method of consuming it that works best for you and what you want out of it.
For instance, if you’re using it purely for pain relief, you probably want the cleanest, most efficient even discreet method—and don’t want to be constantly high.
Whereas if you’re chilling at home with friends, a bong or passing around a fat blunt could be just the thing.
Now on to the main event: How to grow the stuff!
Let’s Get Growing!
Finally, it’s time to talk about how to actually cultivate your marijuana: the different growing methods; which method is most suitable for a beginner indoor grower; and how to avoid poor results.
When it comes to gardening in general, we all know that there are two main ways to grow something:
It’s exactly the same for marijuana.
But which is best depends very much on your circumstances and the results you want to achieve.
What follows is an explanation of both these methods, their respective pros, and cons, how they affect the process and influence the outcome, and how to decide which is going to be the most suitable one for you. We’ll start with growing weed indoors…
Indoor Planting of Marijuana
Growing weed indoors is very common.
On the downside, indoor planting means your plant or crop is not getting nourished in an open-air atmosphere with natural sunlight.
However, with the right techniques, it’s arguably a lot easier to grow quality cannabis in indoor conditions. Mainly because, unlike outdoor growing, when you grow weed indoors you can control and manage all the key growing conditions much more closely.
Advantages of Growing Cannabis Indoors
- The control is totally in the grower’s hands.
- Saves a plant from all the delicate growing cycles.
- More chance of producing the best quality weed.
- You can control and optimize all the necessary growing factors: lighting, air, humidity, water, soil, temperature, nutrients, etc.
- You know when and how to flower your crop, which isn’t something you can control with outdoor planting.
- In indoor cropping, you have total control over the light exposure, which again you don’t have with outdoor planting.
- Direct and too much exposure to light may affect some chemical reactions and enzyme activity. There is no chance of this when you are planting indoor marijuana.
- Because you control the environment, there is less chance of plants getting infected with viruses or harmed by insects.
- On the whole, the ganja community agrees that the quality of indoor-grown marijuana is much better than weed grown outdoors.
Disadvantages of Growing Cannabis Indoors
- Experts who see things differently argue that sunlight gives more effective and healthy nutrients than artificial lighting.
- Various studies show that photosynthesis always works best with sunlight.
- Proper ventilation can be a problem with indoor planting process.
- Regulation of humidity, temperature, and lighting is more controllable but still difficult. You have to be particularly careful with these factors when growing cannabis indoors.
- You can only grow a limited crop of marijuana, as you’re likely to have less space for growing indoors.
- The height of the crop may differ from that of plants grown outdoors, in natural environmental conditions. You may need to learn various methods for training plant growth, to ensure that they don’t get too tall for your space or too close to the heat from your grow lights (even cooler LED grow lights can harm a plant that’s too close).
Outdoor Planting of Marijuana
Outdoor cultivation of marijuana is generally perceived as a difficult task. But, again, ultimately it’s a matter of following the right instructions thoroughly. That said, growing outdoors does, of course, depend a lot on whether you live somewhere with good conditions for outdoor growing and whether it is legal to do so!
We’re not necessarily recommending one method over the other.
As with the best way to consume your marijuana, the best way to grow it is the method that’s best for you and best suits your needs and circumstances.
However, growing weed indoors does allow for all-year growing and will better suit growers where weather conditions are less favorable. So for most growers, that’s likely to be the best option.
Nonetheless, so you’re fully informed, let’s take a quick look at the pros and cons of outdoor growing:
Advantages of Growing Cannabis Outdoors
- The crop gets simple, natural ventilation.
- It’s cost-effective because sunlight is free.
- You don’t need to worry so much about the regulation of temperature, humidity, air, and the other factors that prevail in the natural environment—you can’t change them anyway!
- Yields can be much higher and plants much larger in comparison to indoor planting.
- You can earn more if your intention is to start a business.
- Weed grown in a natural growth environment is much healthier according to some people.
Disadvantages of Growing Cannabis Outdoors
- You have no control over the light exposure. Proper light cycles are one of the most important factors in the production and quality of weed. Too much or too little light can damage your crop and its yield.
- Grow time tends to be longer, and depending on conditions where you live, it may only be possible to produce one crop a year.
- Extreme or freak weather conditions could ruin your crop as could a wildfire that is becoming a problem due to climate change.
- Lack of privacy from nosy neighbors.
- Could be damaged or stolen by others.
- Higher chance of damage by pests, animals, or disease.
- It’s hard to control what strain you’re growing as cross-pollination can occur from wind and insects.
- Also, pollination of female plants can occur more easily, causing them to produce seeds instead of the buds you want to harvest. (Only female plants produce buds.)
Common Planting Mediums for Marijuana
A traditional cost effective and often used medium for growing crops is soil. Soil is (dirt!) cheap and reliable for the growth of any plant. But you should check the quality of the soil and add organic materials or compost to improve results.
The other common medium—especially for growing weed indoors—is hydroponics, a way of growing plants without soil, using mineral nutrients in water. There are various different kinds of hydroponic systems, but they all allow you to grow a plant out of season and indoors.
However, a hydroponic solution needs thorough monitoring. A little error in the chemical solution can become the reason for a whole crop’s devastation.
While a hydroponic approach may get you a good amount of marijuana in a shorter time, there are a lot of things you can get wrong and it’s not a cheap method—so if you just want to try this out, experiment, and learn a bit, and see how a first attempt pans out.
We’ll come back to hydroponics later. But the main aim of this guide is to keep things simple, so we’ll start by describing the simplest solution for a first-time marijuana grower:
Growing in soil, you’ll still get a potent crop, and there’s a lower risk of mistakes and you can get started for a much lower outlay.
Marijuana Grower’s Guide: How To Grow Weed Indoors for Beginners
You’re about to start learning, step by step, how to grow your first crop of lush, green marijuana.
True, there is another way to get started, by taking a cutting from an existing plant and cloning it (we’ll cover that later)…
However, for beginners, we’d recommend growing from seed. The germination rate is 85% or above, whereas the success rate for growing cloned plants is around 50%. And you need to have access to a plant to take the cutting from.
How to Choose Cannabis Seed
The seed is like a sleeping embryo, the result of sexual propagation between male and female flowers. Only healthy parent plants will produce healthy top quality seeds. All the features of the plant, be it the height, color, aroma, or quality, all depend on the seed.
If you want good quality marijuana, you need good quality seeds. We recommend buying seeds from ILoveGrowingMarijuana (ILGM), run by Robert Bergman. He has the experience to produce good seed and guarantee that it gets to you safely and discreetly, and will replace any seeds that fail to germinate!
Some people choose to find seeds in their current selection of buds for smoking. You can certainly get seeds that way, by picking them out before your smoke. But how do you select a seed worth growing?
Avoid pale seeds, green seeds, and soft or damaged seeds. These are not mature or ready for germination. And remember, you are getting seeds that may or may not be chemically treated and certainly are not guaranteed. All in all, buying seeds from ILGM or one of our other recommended seedsmen is a better deal.
Cannabis seeds should have a hard outer shell. So what you’re looking for is hard, dark brown teardrop-shaped seeds, with darker tiger stripes (these are usually Indica seeds) or brown, black, or tan mottling (usually Sativa).
There are numerous strains of seed available. But whatever the strain, you’ll also need to choose between regular seeds that could produce male or female plants and feminized seeds that should produce only the bud-producing female plants you’re aiming to harvest.
However, with feminized seeds, there’s still about a 5% chance of hermaphrodite plants, which produce both male and female flowers and self-pollinate.
(You can also check out our full beginner’s guide to choosing your first seeds.)
Germination of Cannabis Seeds
After selecting the right seed, the next step is germination.
Germination is a process in which the outer shell of a healthy and mature seed, kept in the correct environmental conditions (moisture, air and warmth), breaks down and a white colored root begins to sprout from it, dropping downward.
Here’s what you need to learn: only 2 or 3 out of 10 non-feminized seeds will become healthy female marijuana plants, others may spoil or grow as male plants. So take that into account when deciding how many seeds to germinate.
The average time, a healthy seed takes to germinate is about 2 to 7 days, but the period may vary depending on quality of seed, temperature, moisture, etc.
After the germination process, you’ll be looking to remove all the male or less developed sprouts and focus on raising the healthy female marijuana plants. (More on that later.)
If you don’t have as many female plants as you’d like, you may want to begin another germination process as soon as possible. Our advice is also to germinate in the hot months for more effective results.
A growing/grower mat can help germination too, but is an extra expense.
Once the seed has germinated, the white colored, root shaped sprout should grow longer and longer. When the size reaches about a quarter inch it’s the perfect time to transfer it to another medium such as rockwool tray or any other pot where it has space to become a baby plant.
From there, it will eventually be transferred into the garden, grow tent or a hydroponic system.
How to Germinate a Cannabis Seed
There are many techniques to start germination. But one good tip for the beginner is to practice them on other common seeds first, rather than waste expensive marijuana seeds.
The different techniques for germinating seed are as follows:
This is the most reliable technique of germinating marijuana or any other seed. In this method you need a normal coffee cup filled with warm water.
Put the seeds into the warm water. If some seeds float to the top, remove them.
The next step is to cover the cup with a lid so that light is unable to reach inside.
Expect the seeds to germinate in the following 48 hours or so.
Some seeds will even begin to sprout within 24 hours.
Germination in Soil
Some farmers prefer to germinate in the soil. This method is also easy and it really works.
You need to take a pot filled with soil, pour water in it and let it drain from the hole at the bottom of the pot.
Dig a little soil from its surface and push a pencil or any other pointed tool down about a quarter inch deep. Now put the seed in and then fill up the space with the soil you dug from the surface.
Remember that it will require a normal room temperature to germinate in soil, which is around 78 degrees Fahrenheit. Usually, with this method seeds take 5 to 7 days to germinate.
Propagation kits are inexpensive and give good results.
They will come with their own instructions, but generally you have to pour the seeds into tiny pots or compartments, add the germination hormone or nutrient mix that comes with the kit, and the process gets started.
You can even create your own propagation machine, although purchasing it from market doesn’t cost you much.
Paper Towel Method
Two dishes, two paper towels and some water is needed for this method of germination.
You have to boil some water, rinse both the dishes with it so that there are no germs left. Now soak the paper towels in the hot water and squeeze them so that they become damp and warm.
Place one paper towel on a dish, put some seeds on it, cover them with another paper towel and then use the second dish as a lid. This is necessary to prevent light entering this environment. Seeds will take 2 to 5 days to germinate through this method.
Remember that you don’t want to leave the germinated seeds on a towel for too long. Transfer them from the paper towel as soon as the sprouts show their tips.
Germinating in Peat Briquettes
Soak a peat briquette in water and let it swell. Now push a seed into the hole. Keep it in a hot temperature, like 95 degrees Fahrenheit. Keep it moist and wait for the sprouts to come out. This is the safest and most reliable method of germinating a marijuana seed.
Note that you can select any of the above-mentioned methods of germinating seed. Go with whichever suits you the best.
Once you see that the sprout is a quarter-inch long then it’s time to replant it in a pot, where it will grow up to become a small marijuana plant.
A marijuana seedling is basically a pair of two leaves that is generally called a ‘seedling leaf’ or ‘cotyledon’. The function of the cotyledon is initially to store the food and make the upcoming plant healthy. When the real leaves arrive, the cotyledon gets paler, yellow, and then drops down. Real leaves at this stage of marijuana plant growth have 3 laminae.
At this early stage, a baby plant needs intense care.
Don’t water the plant too much—big mistake. Also, pay attention to the amount of light it’s getting.
If you’re a newbie grower, it’s worth noting here that the growth of the plant appears slow at this stage.
But in fact, what’s happening is that the root system is developing.
So do not over-fertilize or over-water the plant to increase its growth rate. It can kill your plant.
Remember also that the marijuana seedling requires approximately 16 hours of light on a daily basis. Set your light to 15/30/30 (15% red, 30% blue, 30% white) or use the recommended setting if your light has this.
Whether you have your seedling process in a Rockwool tray or in a pot, now is the time to transplant those seedlings into the garden or hydroponic system, where they will start to really grow and produce the material for some top quality weed.
When transplanting the seedling, you should dig a hole in the soil and place the seedling carefully inside.
You can drop the seedling in along with the Rockwool tube, don’t worry. It won’t affect the growth of the plant in any manner, and removing it could damage the roots.
What You’ll Need to Monitor During Growing
Now that your plants are growing and becoming a strong crop, you need to be careful with a few things.
First and foremost, keep an eye on nutrient deficiency or excess. Both can have similar symptoms. But in general, look out for: lightening then yellowing in older mature leaves; spots of different kinds; various sorts of discoloration.
The 3rd to 5th week can be the best time to determine whether your plant is growing healthily or not. If the color of the plant is a perfect green, branches are strong and dense and everything looks fine during this period then you should be satisfied that it is growing the right way.
Sometimes it appears that the stems of the plant in its early days are purple in color. Don’t worry. it’s a normal thing. It happens just because of genetics and nothing else.
Low nitrogen level is good for female plants, while high nitrogen levels produce and nourish male plants efficiently. Too low and you’ll see lightning and yellowing of the leaves.
Moreover, keep the potassium level low for encouraging the growth of female plants and vice versa for male plants. Too low and you’ll see a brown burnt-look to the tips and edge of the leaves, turning yellow further into the leaf.
A general excess of nutrients—usually known as “nutrient burn”—is diagnosable by yellow or brown tips to the leaves. If nutrient levels aren’t reduced, you’ll see the discoloration travel further into the leaf and the tips will start to curl and become brittle.
However, don’t worry too much when you see initial signs in young plants, as the more they grow the more nutrients they need. The soil might be too rich for them now, but when they’re a bit larger it will likely be ideal.
(See our review of nutrients and fertilizers for more info on nitrogen and potassium levels.)
Try to keep control over humidity and temperature when growing weed plants indoors. High humidity helps in increasing the growth rate of female plants, while low humidity is good for the growth of males. Likewise with the temperature: low temperature is helpful for female plants’ growth, while a higher temperature is good for male plants.
Temperature and humidity levels for female weed plants at different growing stages:
- Seedlings: 20-25ºC with lights on, 4-5º lower with lights off; 60-70% humidity.
- Vegetative: 22-28ºC; 40-70%.
- Flowering: 20-26ºC; below 55%.
- Late flowering (1-2 weeks before harvesting): 18-24ºC, 5-10º lower with lights off; 30-40%.
Recommended light settings for indoor cannabis at each growing stage
As far as lighting is concerned, blue spectrum light energy boosts up the growth rate of female plants, producing strong, large, healthy leaves; while red spectrum light when the plants enter the flowering stage promotes budding.
- Seedlings: 15/30/30 (15% red, 30% blue, 30% white). Once the seedling has leaves and has been above-ground a week, 30/60/60.
- Vegetative: 30/60/60, 45/80/80, or 60/100/100 (depending on plant type, check recommendations when buying the seeds).
- Flowering: 100/100/100.
- Late flowering: 100/70/100.
These are the settings recommended by Kind LED (percentages refer to the light’s individual red white and blue settings, e.g. 30% red = red wavelengths set at 30% of full brightness). We’ve reviewed LED Grow Lights lights here.
Many modern LED Grow Lights, especially full-spectrum, have controls to set the right wavelengths at each stage of growth so you have no need to think about the required color. You can just use the control to set the correct lighting for the current growth stage. The same applies to timing if your light has an inbuilt timer.
How to Grow Seedlings into Mature Marijuana Plants
Now you are going to learn the most important things you need to know to become a perfectionist marijuana grower. It’s up to you which method and medium you select to grow your indoor marijuana.
The topics we’re going to cover in this chapter include:
- Growing with Soil Using Germination Process
- Growing by Cloning Process
- Growing Hydroponically
We recommend first-time indoor growers go with the most reliable means of cultivation, which is soil.
The reason is simply that it is a cost-effective method and has fewer risks, compared to other methods.
However, we’ll give you the step-by-step guide for all three of these indoor cannabis growing methods, so that you have a proper idea of what method suits you the most and why.
Growing Weed with Soil Using Germination Process
We’ve already covered why growing marijuana with soil is the best method for beginners. It is cost-effective, fruitful, and reliable.
If you’re not interested in turning this growing thing into a large business, then you may choose to grow in containers.
For beginners, growing in containers is easy to handle and has less chance of failure.
Growing Weed in Containers
Growing in containers, you have a chance to look after each and every plant individually. This allows you to identify weak or poor-quality marijuana plants early.
A container can be of any sort including a pot, small bucket, wooden box, or other similar things. All you need to do is to make some holes (about 1-centimeter diameter) to drain out excess water and get air to the roots.
Make sure that the color of the container is dark, ideally black, as it is helpful in ensuring light doesn’t penetrate to the roots.
You can start off with small containers as they are much easier to handle. But you must be aware that as the roots of your plants grow longer you’ll eventually need to shift the plants (very carefully, so as not to damage the roots) from small containers to the larger ones—usually soon after you realize that rapid growth is beginning.
Make Your Own Container
You can prepare your own container using old and rejected pots, broad-sized bottles, and bowls. You should clean them first and then make appropriate-sized holes beneath the pots. The holes must be big enough to drain all the excess water out. And ideally, the container material shouldn’t let in the light.
Growing Weed in the Ground
If you are growing marijuana at home, then you may not be able to find a suitable space to grow marijuana in the ground, outside, where there is abundant sunlight. But if the option’s available to you, it’s worth doing.
You have to be careful about the spacing of the plants.
Try to leave an appropriate but uniform space between each plant (3-4 feet, or more if you have the space) so that productivity is maximized.
Choosing the Right Soil Type for Cannabis
Remember that if you are growing cannabis in soil then you have to be choosy in selecting the type of soil.
Make sure that the soil you are using for marijuana cultivation is drainable but does not completely drain all the water. It should be capable of retaining some water.
The three factors to consider in the selection of appropriate soil for marijuana include nutrients, PH level, and texture.
Organic soil has the capability to produce the best quality cannabis crop.
The texture of soil also has a major role in the growing process of cannabis so make sure that it is fluffy, light, and can drain excess water but retain what’s needed.
Transplanting Cannabis Plants
Transplanting means moving the plants from small containers to bigger ones or shifting them from containers to the ground of your cultivating area.
The method of transplanting is simple, but not easy. You need to take the plant out of the container carefully, along with the roots and all the soil around them. Dig the next home for this plant from its center and then place it in the hole.
Transplantation can cause a little damage to the root system and some stress to the plants so they need some time to settle down.
We would advise transplanting at night so that plant has an appropriate time to rest before light starts it growing and photosynthesizing again.

Below are the main nutrients which play an important role in the growth of marijuana:
Nitrogen is the most essential element that helps in leaf and stem growth. Too little nitrogen leads the plant’s leaves to turn yellow. So use as much nitrogen as you can, especially during vegetation to make sure that the growth of the plant occurs in the finest way.
Phosphorus plays a key role in the process of photosynthesis and respiration. It is advised to use more phosphorus than nitrogen during flowering.
Potassium is necessary for the building and transferring of sugars for marijuana plants. It is also an important element for the absorption of water and nutrients, aiding rapid growth of the plant.
Watering of Marijuana Plants
Watering depends on the size of the plant’s container and the light’s intensity.
HID lights due to the high level of heat given off affect the water level of the plant.
In general, you need to water your crop every other day. Roots need air as well as water, so a little bit of dryness is healthy for the plant—but not too much, otherwise the plant will suffer from dehydration.
Water until about 20% of the water drains through the runoff hole at the bottom of the container. Then empty the runoff tray, rather than let the container sit in that water and reabsorb it.
Checking pH Levels
The pH level of marijuana plants needs to be monitored very carefully.
6.7 to 6.2 level is the best condition for the survival of your marijuana plant. Not paying attention to pH levels can lead to the devastation of the whole crop.
Overfeeding fertilizers and organic compounds may cause disturbance in the pH level of a plant, so make sure to do your research before using any fertilizer.
As far as fertilizers go, common manure fertilizer will do just fine for marijuana. You don’t really need to find some super extraordinary ultra-nutrient.
So you are now almost done with the main guidelines about marijuana cultivation in soil. The only thing that remains is the level of lighting, which we will guide you through in detail later on after we’ve talked about cloning…
DIY Cloning Method for Growing Marijuana
Cloning marijuana (or any plant where you want a specific genetic profile) is one of the smartest, and least expensive, methods for growing weed indoors and is widely used by farmers and indoor marijuana growers.
How Do You Clone?
Choose some donor plants, then take cuttings from them and grow the cuttings in a separate medium. You’re essentially creating mini-copies of the original plants.
The big advantage is that each clone will turn out to be a female plant—i.e. the kind you’ll harvest hopefully giant buds from.
There are, however, some drawbacks as well to cloning, but if you already have some healthy and productive marijuana plants it’s a great way to produce more.
You can easily select some donor plants from existing plants in your crop and then make some clones out of them.
But let’s have a closer look at the benefits and drawbacks:
Benefits of Cloning
- It is a time-saving process because all you need to do is to select some plants, make the clones and place them in their growing mediums. In the seed method, it takes days in germination, growth of seedlings, and so on.
- It saves money as well because you don’t need to buy any seeds.
- Your plants are guaranteed to be female.
- They grow much faster than seedlings since they’re essentially already as mature as the plant the cutting was taken from.
- Rooted clones of marijuana take less time to flower.
- Growing lots of marijuana at once becomes a much easier process, as clones take so much less time to grow.
- The characteristics of your final product will be the same or even better in taste, aroma, and effects every time.
Drawbacks of Cloning
- Due to the genetic uniformity, there is more chance of plants succumbing to pests and diseases.
- Less variety. If you go with the seed process, you can grow something different every time—try different tastes, aromas, and effects.
- Cloning can be workable and reliable if you are taking cuttings from your existing marijuana plants that you know well. Finding them from other sources and getting perfect results is far from guaranteed!
- If you choose a poor plant to clone from, you’re stuck with that plant’s flaws.
- They can easily die of shock if a little mishandling happens.
- QUICK TIP: Always take more clones than you need to allow for the inevitable.
- Clones are very sensitive, so are not that easy to handle at all.
- All the clones are always going to be females. Which makes breeding a problem in the future.
Step by Step Guide to Cloning Cannabis Plants
Below is the easy and step by step guide to making your clones:
- The first and most important thing you need to do is to choose the mother plant. Remember that all the future product depends on it, so choose a healthy, productive, and disease-free mother plant.
- You should cut 50% more clones than the number of plants you need. Not all clones are going to become healthy plants. Many of them may die from shock.
- You can cut the clones at any time during the plant’s cycle but supposedly the best time is before the plant starts flowering.
- Your hands must be washed with a good antibacterial soap; all your tools and growing area/medium must be clean too.
- For immediate planting, a pH-balanced medium should be prepared.
- Keep all the clones nearby you within immediate reach at the time of their planting; exposed clones will wilt quickly.
How to take a cutting from a marijuana plant
- Select the appropriate clones: actively growing plant tops, having two to three nodes/branches only with fan leaves (mature plants have alternating leaves, rather than facing ones). See the photo below.
- Cut a lower node or two at the stem.
- Treat your clone in a rooting solution fungicidal B1 mix, and make sure at least the lowest node is thinly covered.
- Now fix this clone in a Rockwool cube.
- Do not forget to prep the rock wools by soaking them overnight in a pH-balanced solution.
- Clip large leaves in half to ensure that the clone focuses on creating roots.
Growing weed clones into mature plants
- The next step is dome and lighting. You have to spray inside the humidity dome or propagator with No Damp solution. (This is an excellent step-by-step article on preventing fungal diseases in seedlings.)
- Do not spray the clone direct as it may result in powdery mildew.
- Place the covered clone tray with humidity dome at a spot where an appropriate amount of white fluorescent light is available. This light can be natural sunlight or T9 grow light, or even an HID light if you’re careful.
- The humidity dome should be removed from the clone tray on the 5th day. But remember also to lift the lid daily for air exchange.
- Water every other day. Then once a day when the dome has been removed.
- Now you have to check if the plant is rooted yet or not. For checking, you can tug the plant lightly toward the upward side. If the plant is rooted, it will not come out of the cube. If it is not, it will come out of the cube easily. Please note that you are not supposed to do this until the 5th day. Rooting can take 5-10 days.
- If you see some leaves turning yellow at this early stage, it is actually a good sign so don’t worry. It happens because, during the process of rooting, the plant consumes all the nutrients from its fan leaves. Add a little weak nutrient at this stage.
- Till the time plant is in the process of rooting, you have to spray it with water. Once you have seen signs of plants being rooted, water them properly.
- You should also drain the rooting solution out from the cube as it is of no use now.
- Now, at this critical stage, you are supposed to check whether the plant is wilting. You can check it by opening the grow tent a little bit. If you find no wilting for 4 to 6 hours it means you are ready to move ahead.
- Now you can put these clones under HID or led grow lights or you can plant them outdoors in soil.
- Make sure that they get 15 to 18 hours of lighting. They need this much light to get to the vegetation phase.
How To Avoid Wilting When Growing Clones
Don’t worry if you find your clones wilting, just check if they are placed properly in their respective mediums. Also, keep a close eye on your lighting. It should not be too bright and should be in line with the light levels needed by the plant. New clones need relatively gentle light: 25/45/45 (red/blue/white percentage—see the link above for an explanation of the light settings).
If you follow the above criteria, you should get successful results. And over time and with experience you’ll be able to refine the process and learn even more.
Hydroponics for growing marijuana results in the greatest yields. But it has both advantages and disadvantages, so let’s discuss them first before going into the core details of how you can grow your own Cannabis Sativa using hydroponics.
- There is no need for soil in this method so it is a clean process. All the process is done making no mess at all.
- Due to the controlled system, pollution in the environment is eliminated.
- It produces large amounts of high-quality weed.
- Due to the controlled and monitored system of hydroponics, there should be no dry spots or root drowning.
- It reduces water costs because water remains in the system.
- Nutrients are controlled under the system, so it saves you money here as well.
- It is easier to prevent the hydroponic system from getting infected or attacked by insects.
- The time of growth is rapid and the quantity of yield is greater.
- With the right hydroponic system, you can even grow your own weed in your bedroom.
- This is an expensive means of growing marijuana.
- You need to regularly monitor the system.
- It totally depends on electricity.
- A little mistake can destroy the whole thing that took you ages to prepare.
Beginners’ Step By Step Guide to Growing Marijuana Hydroponically
Now let’s show you how to grow marijuana in your hydroponic system. Make sure to follow each step correctly and in the right order.
- First of all, collect all the basic necessary items that you need. The items may include seeds or clones (whatever you prefer); some white paint; hydroponic nutrients; containers or pots; growing medium for the pots (such as Coco Coir); fluorescent, HID, or LED lighting system; timer; pH detector.
- Now you’ll need to prepare your walls in order to maximize your weed production. Growing indoors means it’s up to you to provide your crop with an appropriate amount of light. Painting the walls of your grow room with semi-gloss white paint helps reflect the light source back onto the plants.
- You can also use mylar to line your walls or grow within a mylar-lined grow tent or grow box, as mylar is highly reflective. The drawback is that mylar reflects both light and heat extremely efficiently, so you need to be careful not to burn your plants.
- Next, you have to set up the lights. Hang them to give your plants the maximum amount of coverage. Your light should come with instructions giving suggested heights for each stage of growth to ensure each plant in your grow space gets enough light. Also check any instructions that came with your plant or seeds, as some strains need more light than others.
- If you’re using HID (High-Intensity Discharge) grow lights, the general rule of thumb is 40w per square foot, going up to 60-70w to maximize yields.
- If you’re using LED grow lights, to ensure good coverage, check your light’s PAR value. PAR (Photosynthetically Active Radiation) is the section of the light spectrum that the plant can actually absorb and use to photosynthesize. This is the range from 400nm to 700nm. A full-spectrum LED light will produce the PAR values you need at every stage of your grow—and won’t waste your electricity bill producing light your plants can’t use.
- PPFD, Photosynthetic Photon Flux Density, is the main measure of how much of that usable light is falling on the plant per square meter per second. It’s basically the intensity of the light. This is often what people mean when talking about PAR rating or values. For good light coverage, the higher the better.
- When buying LED grow lights, as well as looking out for high PAR values, you also need to check out the spectrum it produces. This is basically the quality of that light. The ideal is a full spectrum grow light.
- The simplest rule of thumb for making sure your plants are adequately covered by an LED grow light is to assume a minimum of 32w per square foot. However, note that this refers to how many watts the light draws at the wall socket, not its stated output.
[N.B. We could go a lot more in-depth on ensuring even light distribution, PAR, and the various measures and ratings involved with grow lights. It’s a large and sometimes controversial topic in the weed-growing community. However, for this beginner’s guide, we decided to stick with the simplest rules of thumb, to get you growing more quickly. And as we mentioned above, the instructions that came with your light and seeds/plant should see you right. Also, see the discussion in our Free Beginner’s Guide e-book.]
Temperature, humidity, ventilation, nutrients
- Careful not to overheat plants with the lighting. The maximum temperature a marijuana plant can bear is about 90 degrees Fahrenheit. Check our guide for how to measure and control temperature and humidity in your grow setup.
- Every plant needs proper ventilation. This is one of the most important requirements for an ideal indoor marijuana-growing environment. So make sure that your growing area is properly ventilated.
- If you are not using the cloning method, then you’ll obviously need seeds. Seeds need to germinate before planting. (We’ve covered how to pick seeds and germinate them above.)
- The next destination for a germinated seed is a Rockwool block. This is where the initial growth of the plant will take place.
- Now you can start feeding your plant with water and other nutrients in your hydroponic system. The ideal water pH level at this stage is 5.0 to 6.0. Do not overfeed the plant with some extraordinary amount of nutrients—too many nutes can spoil a plant very quickly. Start off with an average amount of nutrients and increase gradually.
- At this stage, a plant needs intense care and careful monitoring to ensure maximum yield in the future. Keep an eye on the pH level of the tap or filtered water you are growing with. Also, keep a careful eye on nutrients and lighting. As plants grow they obviously get closer to the light, so be careful they’re not getting too much.
Vegetation and flowering
- After seeding, the next important phases in a plant’s life are vegetation and flowering. You need to make sure that the environmental conditions are perfect for these stages to maximize your yield and yield quality.
- You can use height to determine the growth time for your plants in the vegetative phase. The plant may double its height during the phase of flowering. Ideally, the plant should be left in a vegetative stage till its height is 6 to 18’’.
- Once your plant has grown up to 18’’, it’s time to start the flowering process. Balance of lighting has a vital role in the flowering phase. Adjust the light schedule of your LED Grow Lights to provide 12 hours of light a day.
- As plants begin to flower, within the first couple of weeks you’ll be able to judge the sex of the plant.
- Female plants will start growing white hairs around the nodes/branches, these will turn into white wispy almost shoot-like ‘pistils’.
- Whereas in male plants, after a week or two, small grape-like balls will become visible, which will grow into bunches (pollen sacs). These bunches may also resemble bananas, in shape and color. (So, yes, balls and a phallic shape. If that helps you remember.)
- Check, too, for hermaphrodite plants. Sometimes a plant will develop female pre-flowers on one part and male on another. So continue to keep an eye on plants that you thought were female, and don’t just judge on one preflower.
Female on the left, male on the right (see the balls?)
- Remove all the male plants now as they will pollinate females. Also, remove hermaphrodite plants that will self-pollinate and may pollinate other plants too.
- Continue to keep an eye on flowers as a stressed female plant can begin to grow elongated yellow pollen sacs from the center of the bud. These ‘bananas’ produce pollen as soon as they emerge. Remove or separate them immediately, and if you see too many ‘nanners’, begin harvesting and cut your losses.
- Now comes the most patience-demanding phase, as you wait for a plant to reach maturity. How long this takes totally depends on your system and the type of strain you’re growing. As a general estimate, it takes about 6 to 12 weeks for Cannabis Sativa to mature.
- One week before harvesting, only feed the plant with water. If you use other nutrients at this time, they can affect the taste when smoking your weed.
- Harvest when resin on the buds is clear and sticky, some of it beginning to darken to brown or amber.
- For greater control over flavor and effects:
- When you see 50 to 75% of pistils have turned red/brown, you’ll get a lighter flavor and mellower high.
- When 70 to 90% are brown you’ll get heavier stronger weed.
- 90 to 100% and it’s very nearly too late, the taste will be heavy and the effects more narcotic.
- Other signs that it’s harvesting time: the stem will start to broaden, leaves will start to yellow and die back.
- You can also look closely at the trichomes (the hairs on the buds). If the trichomes are clear, keep waiting. If they’re a milky white, some becoming amber, they’re ready. If they’re all amber, you’ve waited too long—your weed may have a very strong, possibly unpleasant flavor and active ingredients will have started to deteriorate. Use a magnifying device to check.
- Or you can just judge and plan ahead by time. Generally harvest Indica after 8 weeks of flowering, Sativa after 12 weeks (10 for some strains), and autoflowering strains (check here to learn more about this) after 10 weeks total from seedling to bud. But always check the likely flowering phase length for the particular strain you’re growing.
How Important Is Light for Indoor Marijuana Growing?
Marijuana requires a lot of light. This is the key factor in producing greater yields. The crop will not be sustainable if an appropriate amount and type of lighting is not provided. Whether you are growing cannabis in soil medium or in a hydroponic system, correct lighting is probably the most needed nutrient for healthy plant growth. We have several articles on how to choose a light, but the most recent and important is our review of LED Grow Lights for 2021 (which of course is updated a couple of times a year.)
Lighting Systems for Growing Weed Indoors
When it comes to lighting systems for indoor growing, there’s an almost overwhelming amount of choice available these days. And of course, each option has its respective advantages and disadvantages—which we’ll cover shortly.
Lighting systems can include bulbs, reflectors, ballast, timers, different color spectrums, and various other features.
But whatever the system, the intention is to activate rapid growth in your cannabis plants and maximize your yield.
The Role of Light in Growing Cannabis
What you need to determine before choosing the lighting system is the color and temperature of the light. Different colors have different impacts.
Look at CCT/Kelvin rating to determine the color of HID fluorescent lights and the CRI rating to gauge the intensity of the color. The higher the CRI the more natural and vibrant the stated colors will appear. For Kelvins, 2700K will be a warm red, 4200K a cooler blue color, 6500K is closest to sunlight; the lowest Kelvin rating is white, the higher the number the bluer the color.
You will find varying advice on the wattage of lights, with the maximum used by most growers being 1000W for the cultivation of Cannabis Sativa. More than 1000W will usually be harmful, but setups with lower wattages can work well.
(However, when it comes to LED grow lights, you’ll find some much higher wattage LED models on the market. One of the great advantages of LEDs is that they run much cooler than other grow lights.)
A simple way to gauge light emitted per square foot by a non-LED bulb or any other non-LED light source: look at a light or bulb’s lumens rating. A marijuana crop needs luminosity of at least 3000 lumens per square foot. Although, for maximum productivity, you should provide 7000 to 10,000 lumens per square foot.
A broader color spectrum lamp will tend to outperform a grow lamp with a higher lumen output. They need bright light, but it’s the blue and red parts in particular of the visible light spectrum that plants actually absorb and use to photosynthesize.
Having said all that, though… we want to reiterate the importance of PAR values.
PAR spectrum emitted by a full spectrum LED grow light.
Lumens really only measure the intensity of the light to the human eye.
For plants, which can only use wavelengths within the 400-700nm range of the light spectrum, it’s PAR that really matters, and the spectrum of light produced.
Various kinds of bulbs can produce a broad spectrum of usable light for growing cannabis. Or you can have different lights for different stages of the growing cycle.
But a good LED grow light is the simplest option. It will give you every kind of light the plant needs (and none that it can’t use), more efficiently, cheaply, and with more user-friendly controls.
However, a lot of available growing advice (especially for non-LED grow lights) still discusses lumens. Hence the discussion above.
If you want to know more, we have a more in-depth discussion of PAR and how to choose the best grow light for you elsewhere on the site. You’ll learn a lot more about the light wavelengths plants use, different types of lights used for growing weed indoors, the best lighting for beginners, and what features to look out for.
Sources of Light for Indoor Marijuana Growing
Growing a crop indoors you’ll obviously need some artificial light source—and you simply cannot afford to ignore good lighting if you are a serious grower and want results.
Fluorescent and especially LED grow lights are great for the growth of marijuana plants.
Compact fluorescent lights are also available on the market, commonly abbreviated to CFL.
The best thing about CFLs is that they are available almost everywhere. HID lights may not be available in some places, but CFL is available pretty much anywhere in the world.
Early LED lighting systems were not ideal, but the technology and costs improved rapidly, and LED lights are now highly regarded for indoor growing of plants. As we said above, they’re by far the simplest option and increasingly the best option too—especially for a beginner.
There are numerous benefits to using LED grow lights, but the one most worth mentioning here is that they produce full-spectrum light with a low level of heat.
Placement of Light
The ideal distance of light from your plants totally depends on the type of source you’re using.
If you are using heat emitting grow lights then you’ll need to place this type of light a bit higher above the plant. Check the light’s instructions. However, if you’re using something cooler like LED grow lights, hang them about 10 to 14 inches from the plant.
Lighting Schedules for Different Stages of Marijuana Plant Growth
During the plant’s different phases, Cannabis Sativa requires different schedules and hours of lighting.
- In the seedling phase, Marijuana needs 16 to 18 hours of proper lighting.
- In the vegetative stage, the requirement increases to 18 to 24 hours daily.
- In the flowering phase, give the plants 12 hours of light and increase the red part of the spectrum.
Remember that lighting plays the main role in the nourishment of your marijuana crop. If lighting is not good enough, your harvest won’t be either.
Harvesting of marijuana
Let’s get one thing out of the way, harvesting marijuana doesn’t demand some sort of rocket science. Harvesting is actually a fun thing. It’s the reward for all the hard work you’ve put into all the growing phases of your crop.
Here’s what you need to know to get it right…
When Should I Harvest My Marijuana Crop?
Let’s cut straight to the chase.
The right time to harvest marijuana is easy. In fact, we’ve already covered it above.
Just look at the color of the pistils or hairs covering the buds.
At the beginning of flowering, they’re white, but when they’re ready for harvesting they start to turn dark brown.
When around 70% have turned brown is a good time to get your harvesting tools ready. After that, it all depends on how you like your weed to taste and the effects you’re after. The browner, the stronger heavier, and more narcotic.
How Do I Harvest My Marijuana Flowers?
On the day you decide to harvest your marijuana, it’s a good idea to start off early in the morning.
Harvesting isn’t difficult but can certainly be time-consuming work—especially if there’s plenty to harvest.
You should start by cutting the plant wholly from its root. Cut all of the plants that you nourished in your grow area. To make things easier, begin by cutting the larger, heavier plants first.
After cutting them, remove some of the larger fan leaves. Then hang some wire horizontally from the ceiling and hang the cut plants from it, upside down, keeping some space between plants for good air circulation.
The cheap, economical, and most reliable way to dry the plants is to leave them in open air.
However, drying cabinets and automated curing machines are also available on the markets these days and can be very helpful in drying your cannabis quickly and efficiently. The latter are more for commercial growers though.
- Environmental Friendly! Breathable Nylon mesh, built-in steel wire ring for steadiness.
- ZIPPER - The length is 1/4 of the circumference. Allows each level to be completely enclosed. Gently maneuver,shake and flip without losing contents.
- Perfect suitable for kinds of plant such as herbs, flowers,and so on
- Foldable design can be fold into a small package for easy stor
- TIP: Be careful when you open the package. A smooth scissors for free
Some people also use oscillating fans to improve ventilation when drying. The fans should be circulating air around the plants, not blowing directly on them. If your plants are moving, your fans are not positioned correctly.
What Time of Day Should I Harvest My Weed?
Time of day is important in the harvesting of cannabis.
Ideally, harvest in the dark. Because at night, the female plants store the food which they prepared during the daylight by photosynthesis.
However, that’s for outdoor growing.
For indoor growing, nighttime is dependent on your plant’s lighting schedule. If lighting was scheduled during night hours, for instance, then harvest the product in the morning.
Since it can be time-consuming work, check how many plants you have, estimate how long it’s going to take to cut them all, and make sure you’ve set aside enough free time to get it all done.
How Do I Prepare my Weed for Smoking?
The first thing to note is that plants don’t die when you cut them, they die when their water is dried out.
So, before doing anything else to your harvest, you need to leave the plants for at least 7 days in an environment of around 70 degrees Fahrenheit and 50 percent humidity to dry the remaining water from the plant.
Keep the room dark too.
And check periodically that no mold or mildew is developing. Remove any affected parts immediately. A fan to increase air circulation will help to prevent this.
A quick note of caution:
During the first few days of drying, the plants will give off a strong, unmistakable scent of marijuana!
But don’t be tempted to hurry things along.
Drying is not a process to rush—it can take up to two weeks. Sometimes a few days longer. However, drying slowly ensures heavy, flavorful, aromatic buds.
After drying, the final step to producing tasty, smokeable weed is curing properly (technically, the whole drying process from the moment the plants are cut is curing).
When the twigs inside your buds become brittle and the outside of the bud feels dry to the touch, you’re ready to begin. The buds should just snap off, with no stringiness left behind. Ideally, larger stems should still bend.
Some growers, however, like to trim the buds before curing. If you do so, use clean sharp scissors to trim away any remaining leaves. (But save them for making edibles, as they will still contain trichomes.)
What is Curing and Why is it Necessary?
Curing is done to make sure certain natural plant processes occur that will ensure peak potency and quality. It gives you a smoother, more flavorful smoke.
Here’s what curing does for your dried buds in more detail:
- Breaks down chlorophyll to improve the taste and smoothness of buds.
- Brings out the unique flavor mix and aroma of your chosen cannabis strain.
- During curing and drying turns all the THC in fresh marijuana into psychoactive elements that make you high when smoking it.
- Reduces “harshness”, so that you’re less likely to cough or get a headache.
- Properly cured buds are less likely to cause negative side effects such as anxiety and paranoia.
- Lessens the risk of mold or bacteria growing on your buds.
- Increases potency, according to many.
As a first-time grower, you might be eager to try the fruits of your labor ASAP. But as you can see, it’s worth waiting—good curing accounts for almost 50% of the quality of your final product!
How Do I Cure My Marijuana?
Simply put the dried buds in mason jars (ideally 1-quart jars, which will hold about an ounce), about 75% full. Any that don’t feel dry to the touch, keep drying them.
If buds already in a jar start to stick together when you shake the jar, they may still be too moist. Just leave the lid off for a while until they feel dry to the touch again. If you choose to invest in a hygrometer to test humidity in the jars, you’re aiming to keep your buds at a relative humidity of around 60-65%.
Also, keep your jars in a cool dark environment.
For the first 1-2 weeks remove lids and check your buds every 24 hours—they need air.
If you smell ammonia or feel moistness, leave the jar open to air for 2-4 hours. If buds feel wet, remove them entirely for 12-24 hours.
Don’t worry too much about over-drying. It’s best avoided, but even over-drying improves the cannabis.
After a couple of weeks, when you’re sure that the buds are curing nicely, you can start to remove the lid just once a week. If all remains well for several weeks, once a month will do.
Buds will continue to cure for up to 6 months.
For long term storage, keep in an airtight container (such as the mason jar). Buds should have been curing for at least 3 months first. After 6 months, consider vacuum sealing them, or freezing the buds in tightly packed mason jars.
How long before you can smoke harvested marijuana?
Up to you. You can try a little at any stage in the curing or storage process and see what ‘vintage’ suits you best.
That’s it—you’re done!
You’ve got your first smokeable crop of marijuana.
