Good morning folks, I had a question regarding UV lighting. I was looking at adding a few of RapidLEDs SEMILEDS ULTRA VIOLET UVA LED (390-400NM) to my current light setup. I'm lighting a 4x4 area. Using 8 CXM-22 @~75w each (the light frame is 3x3). Was wondering how many of the diodes I would need and if anyone has used them? Also can I run these 12hrs without hurting my plants? Any thoughts, suggestions, are greatly appreciated. Thanks!
