I'm on my 4th hydro grow. I've read UV lighting can increase THC levels. Has anyone used UV lighting with any success? I'm running a 4 by 4 drip system with 400 watt veg & 600 watt bloom. If not UV, going to try the G8 LED flower booster. Thanks.

According to that article, it only really effects plants that are high in THC content.
Happy growing.

In my exspereince uv does increase potency and the best light iv found so far is the solistek 10k finisher this bulb is amazing the last 3weeks. Do not use any enclosed fixtures as glass does not allow uvb to go thro it. The solistek 10k wil only work with digital ballasts and they will not work with magnetic ballasts. Eye hortilux also makes uvb floencent bulbs but there not as gd at the solistek bulbs. U can run solistek 10k all the way thro flower but if u use hps for most of the flower u will get higher yeilds then the last 3 weeks switch to the metal halide solistek. But if u run the mh all thro flower ur thc will be even higher! Also the uvb from the solistek helps purple the buds and leaves.Comment

The solistek 10k bulb also will not work on 500w or 250w it will only work on 400w and only digital I bought 2 400w bulbs and learned it the hard way because I have magnetic ballasts lolComment
