Yes, anything over 75 watts per square foot can bleach your plants according to Jorges... I've seen it first hand, straight up white tips on the buds (I hear it is basically inactive too, don't quote me on this though)
I read that 75 to 100 watts per sq ft is the base for an co2 enriched grow space. Just need some advice on the subject. Cooling the space mayb the biggest issue. An yes if was going with 3 1000w hps plus 1 600w hps. This is all for my flowering room though.
Is your flower room separate from your veggie room? Is your room CO2 induced with a controller? The reason for such a high wattage is because the CO2 makes the plant intakes twice as much nutrients and works twice as hard. (At least that's what i read) Im just trying to see this theory proved before I go out and spend $3500 on a new grow op.
