How much more heat does a 1000 watt hps put out then a 600 watt hps? Is it a huge difference? Yield wise would it be worth replacing a 600 watt with a 1000 watt in a 3'x3' closet?
if its used right you get the same bud result as a 1k cause we can run it closer to them and get more lumens pentration...if used right. and is cheeper to run.
