I've already got a 55,000 lumen 400w Hortilux super HPS beating down on one Black Widow plant.. Do I need some extra UVB lights to get the absolute best out of my buds and their trichome production?
If you make sure you get the right one it certainly wouldnt hurt. I dont use any uv supplement but ive been thinking about it for a while. The majority of people i talk to dont.
