Foilage can only utilize so much light...

So if you had a 400W over 2 sq. ft. vs. 1000W over same sq ft....

and one plant...

HARDDON Reviewed by HARDDON on . High Intensity Discharge Variances Could any one clarify the real variances in the growth variations of a 400 watt HPS and a 1000 watt HPS bulb? I know the 1000w is better but where do you think the 400w stands in cannabis growth? Rating: 5
