Another Peltier concept for Cabinet Grows

So,

Most people have heard of these little devices, essentially solid state heat pumps. My thoughts were to get a large 400w unit and use it in a air passthrough system.

So have the in and out ducting side by side with heat syncs fitted in to either side of the Peltier chip, the cold side on the in and the hot side on the out.

Thoughts?

its feasible i guess, but the actual amount of cooling would be very little IMO.
