Hello. I had purchased a grow tent kit (mars hydro) 2x2. Well a week later thought I go bigger so purchased a 3x3 g.t M.H. and t51000. Used the ventilation kit from 2x2 to the 3x3. I have 4 unknown strains in the 3x3 3 gal pots. 3 weeks into veg. My question is should I add the 600w L.E.D (mars hydro) from the 2x2 and use it with the t51000 in the 3x3? Or is that too much?
