I've finished my fermentation chamber and am in need of a heat source. I bought a cheap portable fan heater to plug into my STC-1000 on the heat outlet. The STC is working correctly, I've tested it with good success. My problem is that when I put the fan heater in the chamber and close the door, it doesn't always run when the door is closed and the STC has the heat light on. For instance I plugged it in and left it all night. This morning the temp is at 4* C. It should be somewhere close to 17... The fan runs fun when not inside the chamber.
Just want someone to tell me that it's the fan that is the issue, and that I should go buy a heat lamp. Also what would be the cheapest heat lamp/bulb that you know of?
