Okay, so I'm building an indoor growbox this weekend but do to an extream lack of space I'll only have four feet of growing room (due to the plant tops having to be 20" away from the lights and the 1' of soil). I don't know much about growing but I think they can grow to be twice that tall. Indoor plants are known to be smaller than outdoor plants but will 4' be enough room?
I'm assuming you mean you have 4 feet in height. VEg stage you would only want to grow to about a foot 1/2 or 2 feet max, becasue the plants will double in size during flowering... Can be done. Alot of people grow in computer cases, so i guess you'll be fine to get some bud out of it.
