So I set up a 4x4 in a cold room in my basement

My thought was....

If the cold room stays cold and wet I can program the exhaust fan on the tent to kick in when it it gets to hot. Effectively bringing in the cold wet air that surrounds the tent.

I futher Ensure the air coming into the cold room from outside the house is filtered by a greenhouse hepa intake filter.

Usually in a cold room there is an intake and an exhaust that work passively with dampers to adjust air flow.

In this case I have created 3 rooms in the cold room.

One room is cold and wet. It receives the fresh air from outside. It is circulated into the second room passively to create air flow and keep the second room cool.

The third room is the 4x4 tent which exhausts its heat into the second room but intakes cool air from the first room.

You should see a tent and a small wall of insulation foam board with a hatch.
It stays 10 degrees c behind and at the sides of the tent.
But where I'm sitting and taking the photo it is 22 degrees c
You can also see silver flex ducting coming through the foam board. This is attached to tents 8 inch exhaust fan.
Just to the right of that is a 4 inch exhaust with booster fan it runs on low continuously helping to create air flow behind the tent.

Any thoughts?
