Why do you have to soak Wild Birdseed so long?

Everywhere calls for like 24-48 hours of soaking for WBS in boom teks, but it literally doesnt make any sense to me.

Not that i'm impatient, but it seems really pointless. I'm sure you could just simmer your WBS for like an hour and have about the same results...

Is there anything i'm missing? I feel like people are wasting a lot of time.

Sorry nevermind. Of course i search around forever for an answer, and right after I post this thread I find it...

"Rye Grain. If you are using Rye Grain, make sure to soak your Rye Grain for 12-24 hours at room temperature before sterilization. Lots of nasty endospores, bacteria, virii, competing fungii and a host of other Bad Stuff(tm) are just waiting to destroy your wonderful mushrooms. Allowing the rye to soak at room temperature allows all of the endospores and other organisms to germinate and become suceptible to sterilization. If you use rye and are having problems with contaminiation, try soaking your rye."

I'm sure the rye grain goes the same for WBS.
