I use a 3x3x6 and an open area next and pull 2 to 3 plants every 6 to 8 weeks no problem and keep jars full. I'm sure I'm nothing to you guys but my Autoflower is stronger than anything I've seen around here..humbly I promise. I dreamed of growing since I was 14 and started at 44 so..over 50 now and I just love my cannabis. Pry it from dead hand they will..
