Been working on this all week and just got it rewired and working. Just waiting on my aquarium temp controller to finish it. Turned the lower half of a steel cabinet and a gutted mini fridge into a ferm chamber. All lined with 2" foam and holds two six gallon carboys picture is with a five gallon.
Here's a break down of cost
Fridge $10 Craigslist
Two 4x8 sheets of 2" foam home depot $22 ea
Roll of duct tape $4
Silicone sealant $6
Grand total $64.
