If I mod mine I'm going to try to find a true valve that I can attach to the bottom, something much wider then that little tube. If your going to use a tube like that I'd go for something more like a 1" blowoff type at least.

I have a spectrometer. Is the way to tell if the brew is done fermenting to determine when the specific gravity (or brix) stops changing?

Fermentation is done when you get the same reading 48 hours apart.
