I use a closet for veg now and a grow tent in the room for flower. I cut holes in my door, but I think that in your situation I would still build a box inside the closet. You're going to have a pretty hard time light sealing a hanging, folding closet door. Think it through...Be careful though, lest you need to buy more than one..
Or if you aren't a psycho, and realize you need to keep that 'rrom' secure, a door can be makeshifted..
I have also considered the tent in the closet in the past as well. Not a bad choice. But costly compared to a box. I really only needed two walls and a roof to make mine. I'd bed you could use minimal PVC and some panda film to make it inside your space. Just find a way to attach the PVC to the wall.grow tents. they have rectangles that are 4x2x6 that would perfect. Or two, 2x2x6, one for veg and one fore flower. I bet you could cram 3 plants in there. I will take shit but I do four in veg and flower and if you did it right you could easily get a plant a square foot in each! Exciting. I almost went with a 2x4x6 and a 2x4x6 for veg and flower. That would have been plenty, try the 2x2s!
