Panda film is real nice if you are building a 'disposable growroom'. It's durable enough to be used- and even RE-USED- as a wall material! In a cabinet, I'd skip the insulation- you WANT heat loss!- and go with flat white paint. RE-paint if it gets grubby looking. Exhaust the paint fumes well before introducing plants- get the temps up HIGH to outgas the fresh paint faster.

Odorsoks are neat. Yes, even with a restrictive cooling setup on that 400+cfm fan you can still run one. I think it's in the 200cfm range to work right. Plus they are re-usable, and when you finally give up on them, they crumple up small and fit in the trash. I don't have a huge odor problem at this time of year when temps are lower, but that's my scrubber of choice.

For the LENGTH of ducting in your cabinet, choose ins vs non- insulated. If a lot is exposed, go with insulated, or wrap it in that mylar bubble wrappy looking stuff.

Other stuff I've got no input sorry.
