I had my finger hovering over the buy button for one but they seem like less than a gallon actual capacity that’s why I went with the bags just to be sure i can max out the plant
Another reason is it’s hard to calculate amendments when guessing at how much soil you have
I was gunna run this pot, a “1 gallon” pot from a hydro shop of all places lol, next to a 1 liter bottle of cal mag… yeah… that’s about a half gallon actual pot

here’s my tester plant cman x okie in that size pot, so I’ll be happy to see how much bigger she’ll be in a true 1 gal
