Should i use a 20 gallon or 25 gallon smart pot??

I want to transplant one of my clones into a smart pot i was wondering if 2 baggs of ocean forest that are 1.5 cubic ft be enough for a 25 gallon smart pot or should i just stick with the 20 gallon smart pot ??

well the 20 gallon pot would require 3.1 cubic feet of soil and the 25 gallon would require 3.9 cubic feet. so you could probably use 2 bags for the 20 gallon pot but you would need 3 bags for the 25 gallon pot.

K thanks for the info i think i might juss go with the 25 and buy another bag of dirt
