if you don't have one of those warming belts, what do you guys do to raise the temp in your fermenter?

In a pinch, I once wrapped my fermenter in a string of Christmas lights... Way cheaper than a brew belt, but sort of unpredictable. If it's a glass carboy, you would have to figure out some way to keep the light out of the glass.

I use one of these if heat is necessary...

It keeps the carboy about 10 degrees warmer than ambient usually.

Homemade heat lamp/radiator

It keeps my fermentation fridge at 68 through the harshest of the dreary Los Angeles winter.

i use a heat lamp mounted under the fermenter with a cheap home heating thermostat regulating it, once active fermentation gets under way i put several frozen bottles in the styrofoam box its in to keep the temperature down as i'm not set up to cool just yet, the idea is that the bottles over cool the fermenter and 'fight' with the heating,it cost me nothing as i got all the bits from work and it works reasonably well for now.

Heating pad, push low temp on ale, or make lager. Pick the yeast for the environment, not change environment for the yeast. Unless of course...

same as above, I use a rubbermaid container filled with water and an adjustable fish tank heater. All can be had on the cheap.
