I have grown autos in 4, 5, 7.5, and 14 liter airpots and I prefer the 4 to 7.5 liter over anything larger. The bigger airpots add 2 weeks to the grow to allow the roots to set and yield isn't worth the extra time. I averaged over 2 zips on my 5 liters last time so that's my preferred size for autos from now on.
