They work just as good as a airpot IMO they are a little wider at the top the five gallon but not by much. That being said I have had great success with non woven type shopping bags that are the same material as fabric pots for a dollar canadian a piece. But herculese is a great pot easier to get then airpots they are ridgid and wil last a lifetime you could pass them on to a next gen. of growers airpots if not abused should last a lifetime too non woven fabric pots give or take about five years and to the trash they go
