Are led lights better for growing weed

Since growers are getting such great results with these lights, and they come at surprisingly reasonable prices for LED grow lights, I knew I needed to highlight this company as our most recommended LED grow light!

1.) Spread Style

Here’s a Pineapple Chunk plant I’m growing under the HLG 65 (4000k version) right now. Look how big the buds are at only week 5 of flowering!

3.) COB Style

Grow Space: 2’x2.5′ or 2.5’x3′

Unpacking Existing Information

There is a big misconception in the industry stemming from the LED suppliers that the ability to have your LED lights so much closer to your crop will help increase production lower into the crop. This could not be further from the truth! When your light source is closer to the top of the canopy than the shadows created from the top layer of leaves are much bigger than if the light was further away. (Use a flashlight and make a shadow on a wall with your hand. Watch how the shadow grows as you get the light closer to your hand). Also, light penetration into the crop comes from the crossover between fixtures.

Canopy Penetration

After veg and moving to flower, most growers also agree that switching to a light source with more of the red spectrum is better for flowering. The old standard has been to use either CMH or fluorescents in veg and switch to HPS into flower. This is the tried and true lighting recipe for indoor cannabis growers. By far the majority of cannabis produced in North America today is grown in this way. With the onslaught of LED lighting manufacturers jumping into this new “green rush” of opportunities we are seeing this standard lighting recipe being challenged more and more.
