Can I keep a small rootbound plant?

Hi all, I am attempting to grow 1 plant in a very small space (14"x14"x30"). I am planning to LST the good one that comes out.

My question is, can I keep a plant to maturity in a smaller pot so I can impollinate the other?

The good one will be in a pot of around 1 1/2 gal, or slightly more, so the other will have to to with .7-.8 Gal at most... Will it survive till flowering? Maybe some hard topping... I really just need some pollen from it.

tnx all

Yeah those sizes seem OK for what you are trying to do. Just keep em small, maybe even look into bonsai. (See thread titled "mums")

i did exactly that with a male in a one gallon pot.

My first mom was in a 1gal pot for 6 months and was fine though bound.
