I do have power available and a limited knowledge of it.
I ferment mine in a bathroom that has no windows and 1 small outer wall on the shady side of my house. I keep it in a bathtub of water filled to about 1/3 of the carboy . I drape a wet towel over it that extends into the water. I check to keep the towel wet. This keeps the temp pretty steady. If it starts to warm up, I use a fan to blow air across it. This works very well for me. My biggest concern is the fist 2-3 days of fermentation. I really work to keep the temp steady and in range the first few days.

The good thing about 5 gallons is that it is a pretty big amount of fluid and will take a long time too cool down as you know if you've ever left a bucket outside on a barely freezing night and noticed it didn't freeze at all but there was frost on your car. If your garage hits 35-65 there is a good chance the bucket doesn't cool as far or heat up to the max either, it might never get outside of 40-60.

Ideally you want to keep it in a location that's in the yeast's range like if you have an extra room put it in there and close the furnace vents in that room it should stay around 60 in there if you keep the house at 68 and it's that cold outside.

The big problem with temperature swings during fermentation is oxidation... as the beer warms and cools, it will pull o2 into the carboy and stale the beer. Try to keep the fermentation temps steady if possible.

Thanks Yooper for the advice. We brewed 36 hours ago and we have a cool front coming through and the temp is in the 70's during the day and 50's at night. Seems like the right week to brew in Ft. Myers. I think I'll be using the water bath method as I already keep frozen blocks for the fishing cooler.
