Question about Fermentation Temp and

[PatDaddy]

Fermenter size.

So I bought two, 2 gallon plastic fermenters today, and I'm curious as to how much actual beer these can ferment without blowing the lid off. I was going to do 1.5 gallons. Is a 0.5 gallon head space enough?

And on temperature. I have a laser thermometer that tells the me the surface temp of the fermenting bucket is 62-66 degrees Farenheit. Now I know fermentation is exothermic, so should I be leaving my fermenters in the basement, where the ambient temperature is about 55-58 to compensate for the increased internal temp?

Oh and first post, howdy all.

I've done 1.25 gal in A 2 gal bucket. I didn't have any problems. Not sure about 1.5 gal though. 62-66F should be fine as a fermentation temp. If the fermentation temp gets close to 70F then you might want to put them in the basement until the initial fermentation is over..

Thanks for the reply. Cheers.
