I see you used the carbon air scrubber for the exhaust in the bud dryer. What about using one for the grow box you made http://boards.cannabis.com/growroom-...b-growbox.html

I'm sure there is smell coming out of the box that the carbon thing can eradicate. I guess this could be done by adding a duct on top and attaching the filter.

Also, do you use a lid for the dryer box? Do you put holes on the top. I'm assuming yes.
