Hi Bro!! Well I had plenty of yeast in the house so I decided to try it as an experiment. So I took a 1 gallon jar and mixed my own, I bake a lot so I know a bit about yeast. I'm gonna use it for 3 days and see if I notice any differance at all. With only the 2 in full flower it should be plenty in a gallon. Nothing to lose, so why not right? I'll let ya know, Sis
