I have acquired a 20 cf fridge that will easily hold 3 fermenters. I've got a general idea of what I can do to reinforce the refrigerator floor using plywood & some 2 X 4s, but was hoping to hear from anyone who has done this already. With 3 fermenters, I'm doubt the plastic inside would be strong enough by itself to hold that much weight, but maybe I'm wrong. Anyways, let me know your ideas and/or post pics of your setup. It would be appreciated. Thanks.
