I don’t have dry weight numbers, but I grew 13 autoflowers (11 WW,1 colorodo cookie, 1 pineapple express) in two waves in a 33"x46"x80" shower under 400HPS+400MH lamps. It produced 22 qt sized jars of weed and supplied my wife and I (both heavy users) with 9 months of weed, had to have been around a pound+. They were my first and second grows and I did all sorts of horrible things to them, so they probably could’ve produced even more than that.
