I am ordering an AutoPot system. I was looking at the SoftPot XL version Container is 5 gal and and the XL version of the regular pot they use 6.6 gals. Then looking at their other version (not XL) it is only 3.9 gals. My research has me pretty much thinking prior to even knowing about the AutoPot that 3 gallons is enough for a tent grow 3x4 space.
My question is this: is it worth it to go up to the 5 gallon SoftPot? Is that even necessary with type of system? I am thinking, if I check measurements I can get more pots in the tent with the 3.9 gal version. The XLs would be a tight fit at 4 pots.
