Thought the 2x4 would suffice for veg and I think it would if I could get my cycles down pat. Working towards a perpetual grow. Being a newb there is definately a curve I need to get down pat. The girls are doing very well, and smelling incredible.I decided to drop the t5 down closer to slow them down a bit and it will also cause the side shoots to even up. So hopefully in the next month the flower area is opened up for them!
