My cousin and I are planning on utilizing the fridge. I figure you can use the cooling capacity of the fridge and the humidity control the beads. That way you can have a good fermentation temp then once the ferment is over you can cool it down a bit and keep the chamber's humidity down using the beads
. Using a few pounds of those and a timed computer fan to circulate the air would set you up nicely. If you wanted to drop money there are these very accurate humidity control kits
. I wouldn't put the money into that though because they will essentially accomplish the same thing those beads will.
When I get the set up finalized I'll take pics. I might get the freezer out of my parents house and bring it to my cousin's over Christmas break. The only thing will be buying the beads, and temp controller. The circulation fans will be a homemade circuit that runs off a powersupply or even just a timer hooked up to a big ass lantern battery or two that way the fan can run for a long time and there's no AC to dick with.
