you can buy 2mil plastic, same as you winterize a greenhouse with at a
hardware store and cut it/ tape to how you need. As far a aeroponics,
Google it, I know that at some of the drip system sites online you can
buy micro misters, but you might need a boost pump.

also I thought that catts liked about 50 humidity and could handle
being misted? Mine are getting treated that way, am I screwing up?
(yes I am realitively new)
