Room veg/separation door

[2wheels]

What would be a good setup to go from my Veg. to flower room door. I was considering purchasing a "tent" and cutting the back out that way I would also have a way to hook up a fan for circulation from room to room w/out light contamination. Ideas?

I've seen a few tents that have a big door or a whole side that zips open. Y would u buy a tent to cut ti up? One member used some type of reflective Styrofoam paneling from home depot. It way have been some form of insulation. He used that and duct tape.I believe they have 8X4 tents already equipped with a dividing door in the middle just for this purpose.
