I thought it would be nice to seal the upper part and keep fan/ducting in there but I'm not sure on the ducting and do 'Inline' carbon filters actually exist?

Either two passive inlets would have ability to close off so in cold weather air could come from just the house and not outside.

New to this, any help appreciated.

P.S NOT to scale! The GR is certainly not nearly as big as the house, in fact it is only to hold 3 plants!
