These huge 30 gallon totes with lids are $10 at walmart. I insulated mine with some extra Reflectix. Holds two 7.9 gallon fermenters. Swap out icepacks or frozen bottles and it stays easily in the mid 60's.
I've since upgraded to a freezmenter but the totes worked really well. Swapped out the frozen bottles twice a day.
Cheap and easy.
Went to lowes and walmart yesterday to pick up the materials to make your fermenter tote. I bought two 30-gal Sterilite Totes for $8 each (the biggest they had) and the Acu-Rite thermometer for $7! woot!
I only have one problem, my 7-gal fermentation buckets don't fit! I knew I should've measured before I left but like an idiot i didn't think about it until i got there. My buckets are 17 3/8" tall x 11 7/8" wide, can you measure your buckets for me if you have the chance?
I'm going to the LHBS this weekend to pickup ingredients, maybe they have shorter/wider buckets.
I also picked up the Reflectix but the dolly was on backorder...
I'm almost there!
