I don't see why not, but a 'cleaner looking' solution may be 2" grey PVC. (ending in a 4" to 2" reducer 'T') Just a thought. Shouldn't be a need to glue it together, as it slides together pretty tight.
But, as long as you do something that works, then go for it. :thumbsup:

If doors aren't weather-stripped, air will come thru there, inherently adding to the intake volume. (it'll leak air in, which is ok as long as the light doesn't follow, lol)
Rusty Trichome Reviewed by Rusty Trichome on . Ventallation Question Ok, I have my new cabinet that I am going to use as a garden. My only question is where I should have spaces for ventalation. I am guessing that since there are two sides, I will need two vent's for outgoing, but where should i put them? On the top, or towards the bottom? Or does it matter? I will be using duct fans to push air out (and in, i suppose), so I will have a bunch of 4" holes when its done. Anyway, can someone take a look at the unit here and give me an opinion?
