I was thinking about doing what Khaos suggested and just put a covered light bulb in there at night. That way it would still kick on after it gets too warm.

I thought about moving the jumper on the controller to control a heat source but the weather here is so sporadic right now that I would probably have to keep switching it back and forth from heating to cooling. We're going from 70's some days to 30's the next.

Sweet I did not know that! I can hook a space heater up in my extra room in case temps get too low. I think I lost my instructions but I bet I can find a pdf on the website.

You can get flexible heating film from for $3-4 per foot and make it any length you want. It generates about 40 watts per foot and can be wrapped around fermentors. They call it "Flexwatt" on their site.

Often (perhaps always) these heating pads have automatic timed "safety" shut-offs. Buyer beware.

I just wrapped a brew belt around the upper part of my fermenter.
