Plant height to pot size ratio

Just curious...my space is 2ft. X 4ft. X 6ft. I am using 12inch pots under a 400w metal halide...how tall can they grow???

Sounds like about a 10 liter pot. I would veg for about a month, 10 to 12 inches then flower. They will at least double if not a bit more during flowering. Most in the first 2 or 3 weeks.
 
The strain of cannabis is your first indicator. It also has a lot to do with how much and what kind of nutes you add to it. For example there are some people on here who grow monsters out of Solo cups (16oz.)
 
what would be the only drawback when growing in solo cups 16oz?? rootbounding or would u just have to water everyday?

Yea I would assume they would be rootbound well before maturity. But the growers who do that set-up usually use quick flowering strains....and I'm almost positive they have to go crazy with the nutes, daily doses of exactly what the plant needs. I'm sure the growers who do that set-up are champs when it comes to knowing their nutes :blsmoke:
 
If you ask some. They will say rootbound is a myth. from all the solo cup grows I've seen they are right. down side to so little soil is having to care for them so much more. I use cups but replant at about 8-10"
 
I use a 10" pot and grow 3-4' plants. about 60 days veg and 120 flower give or take. I could ez veg another month or two.
 
ok one more time. My frigging mouse has a back button on it. When I click to post I keep hitting the back button and loosing the post.
I grow in 10" pots 3-4' plants. From the last grow I took apart a root ball. the bottom 1/3 fell away prety ez. some of the side dirt came off and the rest was very tight in the root system. I use a coco blend soil. and water much like the solo cup growers. I use a 1 gal pump sprayer and water very slow. If you like I still have some root balls in the pots I can try to get pic's of it comming apart.
