Good - Better - Best

Words to live/grow by. Sure, you can/have grow decent weed w/o adding UVB to stim THC production. But, if you want your 'girls' to be better and you strive for the best, invest in a a couple of these.

(mine run thru a smart plug and app to on/off the lights throughout a 6 hour mid-section of their 12hr day to simulate real world UVB exposure.)

Great Trichomes

These are great supplemental lights. I bought two of them for a 5x5 area.I grew 4 plants of the same strain with and without these lights side by side and the 4 plants with supplemental uvb have a visible difference in trichome production size and length. They are much more frosty the the plants without the California Light Works Solar Extreme UVB supplementation!

Science

I am just growing out of a 3x 3-1/2 tent for the first time in 30 years. Based on the study from Norway and other testimonials and theory I bought this light. I am only two weeks into flower with my bush filling the space nice and wanted the best product. Got tired of paying 150 an oz for 1 year old weed. Plus its as fun as hell. Wont use it untill the last couple weeks coming up soon. Maybe I will update on my results on my first successful flower project.
