7 gallons is a damn big container in order to use it all wouldn't you need a massive plant or am I missing something here?
agreed i would say you would want to veg your plant for at least 2 months if your going to use a 7 gallon pot. but of course thats just my opinion
This is a little less than two weeks of veg for 2 plants in 7 gal. pots, and 2 more plants that had just been up-canned to 7 gal. pots. The bigger two are 36 days total veg since being up-canned from solo cups into 1 gal. The smaller two I think were 22 days old. In two weeks, the plants were mostly root bound in the 7's.
They are in a 3'x3' space. If they had stayed in there for their stretch, I think it would have been a disaster. In a 2'x2' area, it would still be very full with just two girls, IMO.
