I’ll chip in my two cents on this topic:
I love Panda Film (5.5 mil B&W poly) for lining walls. I have built large facilities using Panda Film to break large warehouses into individual rooms. I use it to line solid walls with a clean plastic surface that can easily be sprayed and washed down. It’s cheap and easy to hang. It’s even easier to tear down. It’s great for commercial and home grow applications.
Happy Growing
