Let's do it.. I here people say it all the time. 1G per Watt, I get lbs off 1000s. Honestly what's your dry? I know someone that thinks pulling 3 quarters off 600 is an easy goal. What's your opinion?
Totally depends on strain and plant health plus light of course. If im growing out personal smoke im happy to get 8-10 oz off a 600 watt hps. Using scrog and 14k watts ive pulled rreal close to 10000 grams not counting popcorn shit. That was in winter with real nice temps. Im sure others have pulled much closer to 1 gpw or more
