You gotta have a lot more room than two feet to flower a 2ft veg plant, like 4-6ft. If you can grow a plant in there you can keep your mother in there. Try not to cut your plants too much cuz it'll stress them out, which could kill them. dun, dun, dunn.
A plant will flower if the amt of light it receives falls below 13hrs (I think anywhere between 13 and 18 per 24 period makes it just do weird slow stuff that's not great but i dunno).
