[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.

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.

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.

  • 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

  • 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.
