How much gram of dry weight

Way too many variables to give an accurate guess... 30-50grams per sq ft in non-controlled environment prolly good ballpark. Whereas, if pumping co2, controlling temp and rh% on top of doing everythgn else in an optimal way might push 100g/sq ft with certain strains. training and genetics just as important if trying to max out. When you cut it down, figure 1/5th of wet weight. It'll shrink quite a bit from what you see on chop day. you'll get familiar in no time.
