It's a 20 gallon pot for the sake of this discussion though that's not completely accurate. A #1 pot in the horticulture industry is not a 1 gallon pot - it's a .75 gallon pot. A #2 pot is not 2 gallons but rather 1.75 gallons. Long story and pretty stupid.Clackamas Coot
What do you mean a #20 Air Pot? Is that a certain size? Can you post a link to that size and the different sizes if that is the case?
