I bow to the great Master of Canniboids wise words on cfl's. He knows much. But here's a good question. Can you have too many lumens per sq/ft? For instance if you had 8 sq/ft of grow space and put a 1000watt hps in there to flower (140,000 or 17,500 lumens per sq/ft), would it just be a waste or would they grow a bazillion mph with buds the size of footballs?
