how big can a plant get in a 16 oz cup

im starting in 16oz cups before going in ground this year and was just wondering how big a plant can get before its rootbound etc, thanks

I have had a Blackberry kush plant in a 16 oz cup for about 2 months without problems....when you star to flower is when the space is going to fill up quick.

Trust me, I've seen some really REALLY huge plants come out of planting them in cups. There was one on this forum, which was HUGE. Depends on your skills, I mean a noob no way, you need some good experience. You can get those plants high.

you can get a decent size plant depending on how you care for it

see if any of these guys has anything going yet

3rd set of leaves in a 16oz cup and the roots are coming out the bottom

i think the roots just happen to hit your drain holes

im pretty sure their is still a good bit of soil space for your roots to take up before you transplant into something bigger

just flip it upside down and take it out ant look at it ,

if your roots are completely covering the root ball then you need to go ahead and pot up

if not just put it back in the cup and you can make a little adjustment so the roots are not coming out the drain holes right off the bat

even put a layer of soil on the bottom or something first then put it back in

they are monster for 3rd set of leaves, been hittin em hard with ferts, but yea i think your right just a root coming out drain hole. im gonna try to get em as big as possible in those because after that there being hiked out into the woods. thanks again

Even if there is no more room for roots, if you keep proving the plant everything it needs, there isnt any reason why it can't grow to its full potential. You should check out the hydroponic threads.
