i dunno, does it matter? no. u do get more lumens per wtt on 600. the 1000wtters give u more space capacity.
JackdaWack Reviewed by JackdaWack on . Growers using multiple HID lights I have a question for some of you growers using multiple 1000w HID lights. If you could do it all over agian and rebuy lights- would you stick with your 1000w or switch it up to 600w?? im thinking of switching to 600's, that is why I ask. thanks for any input!! Rating: 5
