do as you thought...run a small wooden frame around 3x5' where you want to split veg/flower rooms...instead of tarp, use panda plastic-back to back white side out.
Add one of those tarp zippers, s you can access veg/clone/shelf area in back from path along end of room.

Use shelf for little clone area with cfl's and veg under shelf.
vegging plants are smaller so you don't need much height.
you can use cfl's or small MH for veg.

You don't need doors veg area, because of the panda plastic room divider. Actually you would only need small MH for veg and clones if you did this.
hope this helps.
latewood Reviewed by latewood on . Suggestions for dividing closet I've been wondering how to divide my closet up into veg and flowering sections. I've posted some pictures. Closet dimensions are 5' x 5' x 8' H with a clothes hanger bar and shelf in the back at 6' H with about 2.5' of clearance above it. Any ideas or better yet, anyone else have some examples? Rating: 5
