Lighting Question.

I'm just wondering when the plants are in veg or flowering cycle, more so the flowering I'm concerned about. Would a Black light have potential to mess up the "dark" 12hour cycle?

Yes it will. The only light that won't harm the girls is a green light. But honestly your best bet is to just stay away during the night hours. If you got to work in there at night, get a green light bulb.

Alright thanks for the tip dude
