I'm in Ohio. Using 5 gal black fabric and 7 gal beige fabric. It's been so windy here the top part of the soil dries very quickly and is always bone dry. I keep checking it and weighing that against whatever my moisture meter says to determine need.
If I were to grow in pots up here in Ohio...15+ gal is how I'd roll. Too much fluctuating in moisture and temps in small containers IMO. Stable puts buds on the table.
