I'm in the third week of flowering (day 16) my very first crop of indoor cultivated cannabis. I've got 4 bag seed plants and they are doing very nicely .I've kept them small and one seems to be a ruderalis hybrid. I have 4 x 4' led 42w bars and two boards unknown wattage plus 2 x 2' uva fluorescent black lights all wrapped in 98% reflective mylar. QUESTION: does anyone have experience with using black light to increase trichome production? And, do I need more for the amount of space 4'x6'?
