Greenhouses big bang. Is it fem? Check out my U-scrog grow a while back. pulled 5-6 oz off a single plant first go, 250w. I topped and then fimmed. If I did it again though, I would just just top once. Bear in mind I had a badass 6" fan for a minimal 250. Any less and I'm sure I would have got mould. My second grow, I only just pulled it off without mould getting too bad.
