Need help whit entrance

I Have constructed a grow room that is 230 cm long i plan to have two rooms inside one for flower and one smaller for veg. Any smart way to make "doors" for both rooms? I'm useing plastic as walls.

can you make a zipper in the plastic? is it board or flexible type?

Its flexible. I might change it do diamond mylar as the light get thru the plastic.

well if you can get a zipper door sewed it will be cool or you can get those sticky straps on the door to close it
