Pressure Cooking vs. Steaming

I get the impression that PC > steaming when it comes to sterilizing the jars. Is this true? Could someone put a rough number on the % of fails one might obtain from a PC vs. steaming?
I don't have a PC and I don't expect to have one until late summer but I'd like to get a few grows under my belt before then. I'm wondering what my odds are.

Well the reason to steralize is to eliminate all endospores that will grow into contams.
A temperature higher than that of boiling water (212F) must be achieved to kill these spores - i believe its 265F i might be way off on that tho. By using a PC u can reach a temperature higher than that of 212F. By steaming i dont believe this is possible, i might be wrong again tho - sounds right, if not then why the hell did i buy a PC!

Your odds of succeeding when using a pressure cooker go up tremendously, it's a major difference. Yes, you can get lucky boiling PF jars, but that's about it. Grains require a pressure cooker. You can practice boiling PF jars until you get your cooker just go get the feel of things, but PC'ing is a guarantee.

Ok. Thanks for the good advice. I think maybe I'll go with pre-steril bags until I get the pressure cooker.

Yeah you cant even really compare the two. If your going to do this then you need a PC, best investment ever....

grains can successfully be steamed without a pressure cooker at about a 60-70% rate of success(my experience) if a LC is used.

It's all about what you're doing - how you do it. Who cares if I put jars up my ass and concentrate my body's xi to high temperatures if contams are dealt with properly while heating and cooling? Use my asshair as a filter if it works. I've been steaming and boiling my jars, almost all 1/2 pints for a good damn while and have had a shaky relationships with contams but these days I'm always expecting and then staring at 5%-12.5% contaminated jars.
Pressure cookers are aces for keeping water content right in your jars - I mean, since it has pressure (NO AIR ESCAPING YOUR JARS BECAUSE THE AIR AROUND IT IS BEING BOILED AT THE SAME TEMP) the jar's water content comes out exactly like it was put in. Think about steaming jars, water sitting on coffee filters, think about mush in jars that makes contams and the dry substrate that takes a while to colonize.
Hey as long as you're doing what you're doing and you know everything that's going into it. Mycocultivation is an invisible science. Cover your bases. Don't look at me, I'm a hippy just like you.

well you can pick up a small cheap pressure cooker for 30-40$ and you're gonna be really happy with it. It'll cost you less than a 12 pack of presterilized jars. Then once you're ready to get something nicer get a big expensive one and just use the small ones for small jobs. Like whipping up a batch of LC. Or sterilizing a jar of agar.
