5 gallon buckets big enough?

Im planning on growing 2 plants in 5 gallon buckets. "GENERALLY" how large can i grow a plant in a 5 gallon bucket before there isn't enough room for the roots?

i would use a 5g bucket per plant....u can get them at home depot for like 4 bucks each......you could go really big ion those buckets.....but u should crop them so they get fat instead of tall....

You can grow a big plant in 5 gallon bucket, man. If you're worried about it go get one of those 18 gallon buckets from lowes. I've seen people put them in 55 gallon rubbermaid trashcans, and bury them about 3 ft in the groud so they can be managed. You get grow a very decent plant in 5 gallon buckets though.

You will run out of ceiling before you run out of rootspace.

i use a 5gal bucket for my single plant nd there is no worries of it not having enough root space.....
