I've never used fluoros before and dont know too much about them. I have a 600w hps but I think fluoros may be better for veg plus I will be putting together a new room for mother/clones/veg soon. So my question is how much fluoro light do I need for about a 2x2 ft area worth of vegging plants? Also, down the road I will need to use a full 4x2 closet for mothers/veg/clones. Anybody know what kind of heat output that room full of sufficient fluoro light would be compared to a 400w mh?
