bonbon Reviewed by bonbon on . O.K. to flower with BOTH HPS & MH? I started with just a 1000 MH for both phases, but when I could afford it, I replaced it with (2) 600 HPS for flower and a 400 MH for vegging. Now I am wondering if I shouldn't just go ahead and add the 1000 MH back in the flowering room. Here's the crux of the matter. Is it ok to flower with both MH and HPS at the same time? I don't really need it for vegging. It made big buds when it was the only light I had. Check out these beginnings from the MH only. Rating: 5
