Jose.gh Posted August 14, 2015 Share Posted August 14, 2015 Hello, Actually, the UV lamps are used to increase the production of trichomes . But .... they are also very good to prevent fungus. What model you use? Cheers 1 Link to comment Share on other sites More sharing options...

Cannabissapean Posted August 20, 2015 Share Posted August 20, 2015 I had used two 18Watt and two 36Watt fluorescent UV "black lamps" in my flower tent in addition to my normal bud-lamp set-up: (two 270Watt multi-wavelength LED lamps and two 36Watt fluorescent grow lamps). I didn't have any mold issues, but I also didn't notice any other advantage. Maybe "black lamp" produces the wrong wavelength for MJ, so recently I was able to purchase a 36Watt UV-B 2.0 fluorescent tube (for reptiles) at half price. I'll give it a try when the Northern Light clones move to the bud tent. 1 Link to comment Share on other sites More sharing options...
