first off - amazing write up. Just took the time to read through the whole thread and sorry to hear about the flood
you have for sure provided direction and inspiration for me - I am planning to create a cold room - but plan to keep it about 60F - and use an air conditioner to keep it that temperature during the summer months (my last beer got up to 80F and has a ton of off flavors. gotta do something about it and had a free tiny room in the basement and a free window AC to use). Thanks again for the write up and keep up the great work!
