Question about pots

i have all my plants growing in 1 gal pots right now, my question is if i do not transplant them into the ground how much yeild will i get?

depend on how big you let them get and where you have them.

impossible to say. 1gal is fine if you are low on space. but if you have more space, bigger usually=more yield

mine are outside and im afraid if i transplant them theyll either be stunted or ill kill them, and they get about 8hrs of sun a day
