Can I create a sealed space from pandafilm?

I want to create a sealed 10'x6'x8' tent and seal it off, so I can run C02 and A/C in a smaller space and hopefully not have to control odor.

Is pandafilm a good choice for creating a completely sealed off room?

If not, can I run a carbon filter, but exhaust internally inside the tent, just to control smell?

Yep, it'll work. You'll have to use some mold resistant silicon on the seems where they overlap and where they meet the floor. Do it and post some pics...
