T5's..12's envirolites are ok to veg..you can flower with them too, but if you can..no hands down, I'd use mh for veg & hps for flowering.. the fact is more strong light means bigger denser buds and a definite better outcome, so you can use the cheaper fluros for early veg then power up......what does everyone think to useing hps lights or T5 lights i am stuck on witch one to get, anyone got any advice?
