2x2x4 yield expectations?I want to use a 2x2x4 tent, growing (Gorilla Cookies) autos in Nature Living super soil mixed with Coco Loco. I want to yield just a few high quality ounces. Is this easily achievable with one 3 gallon pot under a SF-1000? Should I be concerned with any plant height issues?Setup. Strain - Autoflowering

Light timer ProblemHey Growers.
So I made a dumbass mistakes…..for the last 18 days I have had my light timer set for 12 hrs 15 mins on and 11 hrs 45 off. They are looking good and budding up. I’m wondering is that close enough to 12/12 to have my day 1 flower be true for accuracy sake.
ThanksWeek 7

23 hours light per day?I’m running 4 autos in a 4x4 tent on 20 hours of light per day. I’m thinking about the possibility of changing the light hours to 23 hours a day and 1 dark hour. I’m currently on week 8/9, I’m expecting it to finish roughly 12/14 weeks from birth. Any thoughts on this growers?Setup. Lighting
