Setting up a fermentation chamber with a chest freezer, Love controller and reptile heater bulb.

How much temp swing is acceptable for ale yeasts? I want good fermentation, but I dont want to clamp down the differential on the controller so much the freezer cycles excessivel.

Well, unfortunately, thats all the info I have.
I brew IPAs, stouts, belgians...kinda a bit of everything. Can "most yeasts" tolerate 4* swings? Thats about what my keezer swings and it doesnt cycle too much - once every 2-4 hrs.

Oh yeah 4 degrees ought to be fine. That swing is just ambient temp in the fermenter. With a swing that low the beer wont even move half that much.

Four degree swings, or four degree range? I.e., do you mean 64-68, or within four degrees of 66? The first is fine, the second is a bit much for my experience.
