PF jars can be boiled in a pot for 1-2 hours. Why go through the trouble of attempting this in an oven, when you can do it in a pot on the stove top? Success stories from oven sterilization are next to nil.

I have thought about it, but I have 100% success with pressure cooking, Ive just never taken the time to figure out a way to do it.

after the jars are preped, it is unlikely to get contamed by anything in the air at that point. if you are following the pf tek, you should have NO prob with boiling the jars... the foil you place on top of the lids keeps any water from slashin into your jars

How did you come to this conclusion? The technique you stated was "He places the jars in a metal pan with a few inches of water with a layer of aluminium foil on top", and then sterilize at 525 F (275 C) for two hours. Water boils at 100 degrees C (212 ?F), so wouldn't you expect a bit of boiling, bubbling, and churning with this arrangement? A bunch of jars submerged in a pan of water in an oven at 525F sounds way more risky than boiling in a pot to me.

So, if the water surrounding the jars never actually boils, what makes you think the temperature of the jars will ever reach sterilization temperature?
I'll leave your thread, but I want to leave you with this: Water transmits heat 10x more effectively than air, and that is the reason oven sterilization is neither effective, or a common practice in mushroom cultivation.

When was the last time you were in a sauna at 212F? Try stincking your hand in the steam from a kettle and see what happens. The water in a pan in an oven at 525 does boil, but it boils only from the surface. You should see the steam coming from your stoves vent. The water will eventually boil away.

Just because people like Diver dont feel like going through finding all the failures that have littered this forum over the years with posts such as this, doesnt mean shit. Theres a FAQ that states that it can be done, but will give incosistant results. Thats all the info you need. If you want to know if it works, yes it can, occasionally, and ineffiently I have seen far more failures when this idea comes up (every few weeks, what you think your the first?) then successes. And not many who are still here, have tried it, so you wont get many people with actual experience in doing it, and those that do have experience with it, dont recommend it, so doesnt that tell you something?
Diver may not have tried it himself, but when youve read dozens and dozens of people telling how it fucked up, and the rest saying how it worked, but that its worse then doing it in a PC or pot...well, you tend to chime in and recommend against it. Doesnt mean you need to jump down peoples necks and start being a dick to them just cause they're trying to help you out and its not to the extent you want. Were not here to sit here and work with everyone on their ideas for hours and hours..were here to tell people the best ways we know to grow mushrooms. You dont like it, piss off.
Sorry I'm bitching at you for Diver, I'm pissed off at all the recent people with no posts, comming in and bitching at those of us who dont feel like explaining over and over again the failures that come through this board that we have read over the years..but when you read EVERY post EVERY day on this forum, for months and years..you'll understand. Basically just boils down to, you read the success story in the FAQ on how to do it, put them in a pot with water, just the same as on your stove..try it if you want, dont if you dont want to...but so far your treading into territory where 90% of the people fail.

I think your mistaken about your sauna temp. You may want to take a thermometer in with you next time

Lakefingers said: So, you have any experience with this?
Yes! It's a very inefficient way of accomplishing a simple task. It takes much more power and time to heat an oven and it's contents to 212. A covered pot of water will serve you much better. A pressure cooker is the best way to go, but sometimes we have to make do.
That being said... It's a hobby... try different things and see what works best for you

Lakefingers said: I was also thinking that another problem with raising the temperature to as high as that guy did is that the jars would dry out, and/or the nutrients in the substrate would be destroyed.
Quote:
Lakefingers said: He claims to have had a 100% success rate (no contamination) in all jars he has prepared, inoculated and birthed.
I think you should ask the guy if he was bullshitting you or not and try it for yourself. You seem to know a lot about this oven sterilization process. Enough so that you are debating with others who are knocking the idea. Most people don't use the oven for sterilization and that's why you will more than likely not get an answer to your questions. Perhaps you can become the spokesperson for oven sterilization Pressure cooking and boiling seem like much better options IMO, but to keep the torch lit for you- "Does ANYONE have any experience with this?"

BTW, I do think he could be correct on the suana temp. High humidity in the suana would allow for higher temps to be reached for us to stand it. Typically suanas are less then 80C, but they do get to 100-120C.

You will have the same problems as with the microwave, moisture loss. If you are putting them in trays with water which are covered then you are bascially just steaming them like on a stove top, but in a much more inefficient manner

this is a little off topic, but i had an idea that maybe a Dishwasher could be used for sterilization of PF jars. Last night i tried this. i put 4 jars in seald ziploc bags in the glass rack on top and ran thru once with no soap. the other 10 i did with a pc. if anyone is really interested in this i can post results later in another thread...just tryin to be innovative...but sometimes you just gotta do what works...buy a fuckin pc if your serious about cultivating

That is definitely inovative, but you are using a lot of electricity like that.

Dishwasher was tried before and failed. The top sticky post has a great guide for searching, most of these ideas are old, problem is people try them, fail and don't report the failures.
