how to seal this basement room ceiling?

[tdawg3801]

so i plan on having a CO2 feed in here. the room needs to be airtight.
what should i use for the ceilings? (floor of main living area)
i have plans for the window, the walls, and floor. unsure about ceiling.

i feel like a paint that seals would do just fine

Nice area.. I likes.. styro insulation panels (quick cieling fix) if needed.. poly plastic roll... quick benefit of locking in heat..vapor.. depends on current and future exterior environment.

Why not use tent? Higher humidity might not be very good for wood.

I would get some white 8'x4' 1/2" PVC sheets and silicone all the seams, my local Home Depot carries them.
There's companies that make PVC panels specifically for grow rooms also, even ones that snap together so you can build a room inside a room.

a roll of 6 mil poly and a couple tubes of acoustic caulking will be the cheapest , fastest and best IMO

I used to install FRP panels on commercial jobsites.

Fiberglass reinforced paneling.

You can buy it at Home Depot and Lowe’s in the states

Maybe some waterproof sealant could do the trick.
