[UPDATED] Things are going well on this end. We really appreciate all the interesting comments and questions we get from you and truth to tell, we never really thought we were getting such a large readership. Anyway, we’ve gotten a lot of questions lately about the significance of red and blue lights in the hydroponic plant grow lamps, so we wanted to go over this importance and explain why having a lamp like the Roleadro GalaxyHydro 300W LED Grow Light might be a good idea for your indoor growing.

The Importance of Red and Blue LED light

Hydro culture studies now show that red and blue LED light offers more effective plant and development growth for indoor hydroponics and that this light spectra and intensity when controlled by a grower can make marijuana plants sturdier, greener and overall, more proficient. Which is why growers are increasingly using LED lights for hydroponic growing.

Roleadro GalaxyHydro 300 Watt LED Grow Light: The Specs

The Roleadro Galaxy Hydro Series 300W LED Grow Light full spectrum hydroponic plant grow lamp meets many of these needs.

This is a lamp that is made with more red and blue light than white; which means that if you notice your plants just don’t seem as bright-eyed and bushy tailed as you would want them, you might want to consider using this lamp instead of those that have more white light. It’s also got some decent PAR values for the money—brightness on a budget.

This lamp is well built and considerably sturdier than many on the market. It weighs about 7.6 pounds and measures 15.8″ x 8.3″ x 2.4″. At a very affordable price, it offers a lot of get up and go, as it has a 2 year warranty and a zero maintenance cost.

The high power Epiled 3W chips allow for energy saving but a high brightness and IR (infrared) glow that your plants need. This offers the best ratio of red and blue light which improves the growth speed of your marijuana.

But best of all it also includes IR functionality for even more output.

The benefits:

  • IR for better photosynthesis
  • More red and blue light chips than white
  • Sturdy build
  • High brightness
  • Low power consumption
  • Integrated fans to lower heat consumption
  • Daisy chain more than one unit together
  • 300W HID equivalent—but actual power consumption of around 140W
  • One of the best 300W LED grow lights on the market for the money

The lamp also offers 90 and 120 degree view angles, allowing you to adjust according to the placement of your plants, and although seeing the IR lights with your naked eye is a bit tough, don’t think they aren’t working. These are important and play an important role in the flowering and seeding stage of your cannabis plants.

You’ll want to keep your lights on for 10 to 16 hours a day and change the height to between 12 to 56 inches depending on the different growing stages of the plant.

Bottom Line

Buy this light if you’ve got a smallish grow area, 2′ x 2′ for flowering and 3′ x 3′ for veg stage (and if you know about plant training, you’ll get even better results). Excellent light for indoor growers on a tight budget.

For the price, the Galaxy Hydro 300W grow lamp offers that needed brightness boost for your hemp plants. The red and blue intensity can really make those leaves green and give your plant the needed flavor to make your bud crop outstanding. The frame is sturdy and ready to plug in. We find the cord long enough to reach most power outlets and the easy clip on feature is great because you can change the lamp to different sections when you need to.

A fully dimmable model is also available, if you prefer dimming the brightness to changing the hanging height.

    I’ve been using one of these for 2 years in a 2’x3’x5′ space. I have passive intake venting into my attic and a small circulation fan. I keep it 24″ to 18″ above for veg and when I switch to flowering the stretch brings my canopy to 12″ to 10″ below. Temps stay between 75-81 in summer 68-78 in winter. This light is very bright and I’ve had zero problems with it.

    the globalstar 300w lamp provides 150w in each mode… right? and 300w in full mode? … do you have any idea about the lumens that produce in bloom mode? I dont know yet about getting this one or the Galaxy Hydro 300… I need to maxime the production of a 5 sq ft indoor. What would you recommend?

      These draw actual wattage at about 130-140ish total. There are no modes, on or off, thats it. Its a “300w” equivalent replacement, meaning its supposed to be as effective as a 300w bulb.

    I’m thinking about doing a grow with about 6-8 plants in a 7′ by 6′ grow space I was wondering if 2 of these 300w galaxy hydro led’s would be enough light to cover that space and plants

      Two of these lights without vent fan will send a 3×3 tent to over 100degrees F

      Sorry, hit wrong reply button.

      These lights are good for about a 24″ square space at 36″ above, higher then that, light penetrates less.

    Cali’s new 6 plant rule has me wanting to have a small indoor Scrog grow: tent, LED lights and hydroponic resovoir. I was considering 1 or 2 plants in a 3×3 tent under either a pair of Galaxyhydro 300 W lights or a single 600 W LED light fixture. My question is that I’m unsure which light setup would work best considering a slight cost increase for the pair and factors like power usage, heat, lens directionality and more. I like the idea of using a pair should one fail and more flexibility in placement. The lens directionality baffles me. Also, does the 600 W fixture penetrate a Scrog grow better than a pair of 300 W units? Since a 3×3 tent is taller than many rectangular ones having approximately the same grow area, would heat be a factor in my decision? Can you advise? Thanks.

      Hi John,
      Congratulations and happy growing!
      LED lights don’t generate much heat at all. That’s nice for scrogging since they don’t burn.
      When it says something like 90-degree lens or view angle, it just means the light comes straight down. 120-degrees and the light angles out more (like the Galaxy Hydro 300W). Just one 300W is enough for a 3×3 space.
      If you buy a good-quality light, you shouldn’t have to worry about failure, not for a long time (although crap happens).

      Two of these lights without vent fan will send a 3×3 tent to over 100degrees F

      And only one in that space, 3×3 is minimum… two gives best lighting for that size, as these lights are only about 140w actual draw..
