LED Grow Lights for Marijuana

A couple of years ago if someone mentioned LED Grow Lights for growing marijuana you’d surely hear a chuckle. Now? Well, this light source is quickly gaining respect as an excellent grow light system.

Here are some of the reasons why:

  • Using LED’s for growing saves around 80% from your energy bill vs. HPS and Metal Halide. This is a green solution which is not only easier on the environment, but also your wallet!
  • Low Heat. How many times did you forget to raise your HPS light and burn the tops of your plants? LED grow lights emit very little heat. This also means your grow room won’t be so hot, so its easier to control temperature. Your thermal footprint will also be less, providing a more discreet growing experience.
  • LED growing lights have a long life span. Most are rated for 50,000 hours!
  • Wide Spectrum. The LED’s provide the right blend of light to be equally effective during vegetative and budding stage.

LED Grow Lights and Marijuana?

Yep! LED’s are a great light source and are proven to grow marijuana. They are a great inconspicuous way to grow. A 90 watt LED light system has the same output power as a 400 watt HPS or MH bulb! Just by reading the point form info above you can see a clear picture of why the LED Grow lights are great for marijuana.

  1. What is the recommended color spectrum for each growing phase? I’ve found a company that custom makes each light by allowing the buyer to choose size and color(s). Better yet are there any suggestions about where to purchase led grow lights specifically for growing pot for a reasonable price? Thanks!

    • Hey Abby, yes there are recommended spectrum for each phase. Some lights have both spectrum’s built in. If you’re looking for a good company with great pricing check out DormGrow.

    • Hey Abby. Yes there’s a certain spectrum that is perfect for the growing phase and bloom phase. These are the spectrums that will work the best. The ratio is what you will need to find out if you will be having an LED light custom built, 660nm (Deep Red), 465nm (Deep Blue), 620nm (Deep Orange) and white 6000K.

      I buy my lights from the sites below and have excellent to max yields for the plants:


      If you are only doing 1-4 plants in a 4×4 space you can use 1 90watt UFOs per stage(veg/bloom). But I would, if you can afford it, use the 180watt Advanced Spectrum Quad-Band LED Grow Light Panel from GrowAce for the bloom stage in a 5×5 space or smaller. 60 Watt Advance Spectrum MAX 3w-Chip Quad-Band LED Grow Light for any space larger than 5×5. If you have deep pocket I also like the Solar Flare LED grow lights by California Light Works. If you have a really big room you can scale 10 of them together.

      If you need any help with lights, germination, problems you run into, setups, anything relating to this just message me by replying. Happy growing! :)
