I need to turn a refrigerator (no freezer attached) into a fermentation chamber temporarily. I need to be able to bring the internal temp to between 85 and 90 degrees, with a humidity of 85%. I bought an expensive temp/humidity controller which doesn't work and I have to send it back to be fixed. That leaves me with trying to adjust things manually for a couple weeks. With the fridge unplugged, all I need to do is bring up the temp and the humidity for a while, right? I thought if I used a plug in light socket with a built in dimmer switch, that I could use a 60W bulb, and regulate the heat by using the dimmer switch. The humidity will be supplied by a humidifier that has an adjustable knob. I have a wireless temp/humidity sensor and reader so I'll always be able to tell what it's like inside. Could I have some comments please from those of you that are operating a fermentation cabinet, as to whether this could work temporarily? Thank you.
