1/2 gal pots for rooted clones??

so just a quick question for you guys this time.

so im on my fourth grow session, and i think ive gotten pretty good at it lol
anyways i got some grand daddy purps clones, and the person i got them from did no training on them at all. so they just grew too tall to what im used to. (limited height space)

well anyways i lolli popped them and in the process turned some of them into more clones.
10 in total.
its been about 10 days since then, and 8 have gotten a good root system so far. other two have roots just not long enough for my taste.
so i was thinking of putting them into 1/2 gal pots just to let them root better, and then transplant them agian into bigger pots once im ready to let them flower.

so is this a good idea? or am i going to small?
oh and i was cloning them in rapid rooters.

it ill work just fine . but again unless you need to be in 2 different pots space so on . if not you can just drop that rooted clone into the final pot size. I go from a Dixie cup up to 20 gallons pots .
