I can get a lot out of a 2 gallon pot, but I prefer 3 gallon pots...don't know why.
I apologize for my incessant rambling, but if you are patient there is inner hidden wisdom in most of my posts...Like playing literary "Where's Waldo."--------------- See, it's fun!
I think it is a bad decision to assume the auto pounder you put in a 2 or 3 gallon pot is going to yield anywhere close to that much weight. You're relying on what you have read and unfortunately the majority or what is posted is exaturated the same way as fish stories. Not to mention, with an auto, you screw up one single feeding or temp or whatever, and your yield is effected. Maybe you're an amazing grower and know your shit, I have in fact seem a journal where someone pulled a little over 4 ounces from a "think different" auto and that was in hydro with a 1000 watts, but that a far cry from a pound.
Fantastic Auto phenos can be far and wide and putting all your faith and attention in to one or two will not give you what you're looking for. I am not at all trying to discourage you I'm just looking out. You want a pound? Use a known consistantly high yielding photo like critical mass, shoot for 4oz from 4 plants in 3 gallon pots. If you fuck one up you've got 3 more, and since there are 4 you can keep them short and get dense nugs all the way through. Or 6 in 2.
I will bite my tounge and be proud of you if in 70 days I'm proven wrong.
