7lbs LOL, that's not gonna be close to 7lbs. That'd be 1pound per plant or 16 ozs per plant. It's not realistic. Rule of thumb for experienced growers is 1gram/watt, 2grams/watt is really amazing and many experienced hydro growers see 2g/watt as great. If you want any more than that and you're probably gonna have to do a coli.

2lbs/1000 watt is what the folks at advanced nutrients claim their cannabis specific nutes can give you, with CO2 in a sealed room with completely controlled environment.

I'd guess 1 pound, 16oz dry manicured weight.
