i'm using the ag pro, havent changed anything, got mastergardners kit, so using the ag neus, i germed in the ag in 2 days no problems. now i'm ready to flower but having trouble. i am going to rep;ace the ag lights with 2700k, found on the net with the right connections, am also going to put a couple of cfl's on the side, but have to wait for pay day which means no buds for christmas. also have put a reflective sun visor behind for more light. but its perfect for veg as is, in my opinion.
