from my experience a 1 gallon bucket plant yields around 10-15 grams dry, destemmed, cured flowered at 8" and trained. My last grow was done in 24" with pots 8" tall so more like 16" for the plant, the four females produced 30 grams dry (very poor, I didnt veg with hid lights, bad timing, all sorted out now.). I now transplant to 2.5 gal pots and have more room, but plenty of "practice" plants can be done in 2 feet vertical.
