Changing pots in flowering period.

Im using autoflowering that means it will go into its flowering period in about 2/3 weeks...so nice and early to determin the sex, my problem is im germing six seeds till i can find out the sex because to grow large plants i only have space for about two of them, if i leave them in the small cups 2"x2"x3" until i know the sex, i wory that they will become rootbound, i assume this means that the plant will, once rootbound, never grow any bigger depsite putting it in a larger pot?
will this be the case?
Cheers Jolly

My problem is I have no idea what you mean. Some strains will flower whether you change the light cycle or not. There are not a lot of those.

Uhhh....if you try to leave them in 2" or 3" pots until you can determine thier sex they will be dead first.

i assume this means that the plant will, once rootbound, never grow any bigger depsite putting it in a larger pot?

Sorry we weren't sitting in front of our computers from 4:00 to 6:00 on the fourth of July to answer any well thought out questions you might ask. I would guess most people were confused about the information you provided. VV

yes the point is that Auto flowering plants AUTO flower meaning they go into flowering in 2/3 weeks wether i change the light cycle or not, i didnt mean germing the seed till i can determin the sex, bad wording on my part sorry,
and they only grow to about a foot anyway so assumed small pots would be alright...and why would they die from being in a small pot? wouldnt they just grow to a certain size and stay that way? which is the question i was asking...
sorry for any misunderstanding of my part
