Mind if I ask why you recommend I don't Bobabouy?

So that would mean you prefer sterilizing your casings correct? or do you do both? Really don't want to get my PC out if I don't need to, its deep in a closet, very deep.

why do you need a PC to sterilize them, I just use boiling water to hydrate

Casing sure helps me  Jiffy mix is too easy not to case. 50/50+ is really nice too, as had been said.

oh thought sterilization had to be done by pcing, my mistake I'll go with that then, I'd prefer to case this one I really prefer the idea of casing my tray and i have exposed grains forgot to cover with a layer of substrate at the end and I wana cover them up now, make me feel a lil better I guess.
I'll post pics soon if the flush is worthy

sterilizing grain sure has to be done with a PC, but sterilization happens in 10 minutes at 170F, 10 minutes at 170F is past pasteurization
Quote:

170F for 10m is partial sterilization.
https://en.wikipedia.org/wiki/Sterility_assurance_level
for lab work, hospitals, research, etc... the standard is 6 log reduction after reaching theoretical 0. so if you have 1 million contaminants you need overall 12 logs of reduction. 6 logs to get from 1,000,000 (10e6) to 0 and then 6 more logs to get to .000001% 910e-6) chance of a contaminant.
sterilization is a tricky word. some people learn in their textbook it means what it means. nothing is alive. but in practice you can't actually have a probability like that you can have a probability that 1/10th of an organism is alive. but that's not as good as 1/1000th a chance. etc...
same goes for pasteurization. the stuff they do for milk and juice doesn't apply to us. in the industry they measure pasteurization in PUs(pasteurization units)
we pasteurize for a balance of thermoplastics in our substrates(other than coir)
so yes 170F sterilizes. boiling water sterilizes. but pressure cooking gives you the sterility that we need in this hobby.
170F water kills more than 99.99% of organisms after an exposure of a few seconds. it's a kind of sterilization, it's better than disinfection or sanitation but it's not as good as we need for grain

you achieve baseline sterilization under boiling temperatures on surfaces like stainless steel. when sterilizing transfer lines for beer that can't handle 212F heat you can pump 180F water thru and know it's not going to be an infection risk. but sterilization of already clean smooth surfaces like stainless are much different and don't mean shit when you try to correlate it over to soil dirt coir or grains
