Container Size

Hey right now I have 5 plants which range from 6-8 inchs tall they are all in red dixie beer cups right now. I was wondering if I woud be able to keep these in these cups in anyways without transplanting them because I have limited space and have am about to start up a new aeroponic setup so these other 5 plants would need to take up the least amount of room as possible. So if i give them nutrients etc is it possible to keep them in these beer cups? I plan on starting to flower them at 12inchs, I grew them from seed and they are just over 2.5 weeks old.

u can but there gona top out like 6 in wit out transplant cus thell get root bound and stop growin,i think if u gave them nutes it would cause thom t o get root bound quicker.not sure but just a guess bout nutes

if your have them in soil stay in soil. if you want aero you need to use soiless medium. If your using seeds and in party cups i would transplant them into one gallons within a week or so if they are already 6-8 inches. Its best to let the root structure build up good in the small cup so transplanting is easier and the roots are strong.after they get root bound in one gallons move up to 2 gallons.
