Ferm Chamber Update

So here is the main idea.

I will build an insulated structure to house two carboys with some wiggle room for a starter or one gallon experiments. The tricky part is the heating and cooling (yes I have decided to have both options available due to the rapid changes in the north east and my crappy Apartment).

Here is a VERY rough lay out of the design. I’m stuck on how to wire the submerged pump and the fan to the same power source.

Any ideas? Feed back is always welcome!

Best.

Looks pretty good.
