I got a question...You said your broke...he said order it...then heeee said, He said He was broke...What I want to know! LOL How were you going to buy Mylar in your hometown?..if your broke

Anyway, sLOL, stinkyAttic was right on...you would have to paint the "mud" before it could be used for the inside of a grow room...I would just stay away from drywall "mud" in the growroom, period!

Just paint with flat white, a primer sealer is a good idea for longterm permanent room, but not necessary if you are on a budget...peace:smokin:
