Sterilization Teks?

I need to know a good way to sterilize without a pressure cooker. I have no access whatsoever to one. What I do have access to is a microwave, and some pots and stuff. I was wondering if it will work just as well as a pressure cooker to let the jar sit in hot (160 degree?) water. Would it work to use a microwave? Please help, its real important. Feel free to list any other ways you know how to sterilize.

well if you just want to sterilize PF jars you don't need a PC. Just boil them in an ordinairy pot for 60 to 90 minutes and that will be fine. For grains you need a PC though no way around it. Casing material you can do in a microwave no problem, but until then you need to worry about colonizing your cakes first...
I beleive there are possebilities of maniging fairly well via the use of a lot H2O2 but I'M not sure of the procedure nor what it is suitable for... either way I don't think its advisable.

Other than using a PC, boiling is probably your next best option. As opposed to a 45 minute PC time, you will have to boil for approximately 1.5 hours. From what I hear this is a questionable method of sterilization. Many people suffer from 100% contamination despite the boiling of their jars. For more info I believe there is a more detailed description of the process in most of the PF-Teks.
Good luck Cap

160* is pasteurization, not sterilization!!

160 will not get the job done. Boil the jars just as you would PC them (keeping the water level several inches from the jar tops, use foil on the tops, boil for an hour) For me, this resulted in about 25% contamination (acceptable since I didn't have a PC at the time). A better thing to do would be to boil the jars, let them sit for a day and boil them again. I haven't done this but others have. You might want to add 1-2 additional CCs of water, but I have never read specifics on adding additional H2O.

well im planning on using the pf tek. the one with brown rice powder and vermiculite as the casing. does that count as something that *requires* a pc?

The PF tek is the ONE tek where you're ok (in a subjective way) not using a PC. Whole grains are to insulated for boiling to kill everything, but your chances are better with flour.
But look at it like this, once you get that first batch, you'll realize you want to do another one, you'll look at the fact that you had a few contaminated jars, and then you'll likely go out and buy a PC. Why not just go buy a PC now? Let's say you loose 3-4 cakes due to contams. for 30-40 bucks you can save those cakes and get more shrooms your first time around, and you'll be ready to do it again, or to try your hand at whole grains. When I first started, I was hesitant to buy a PC, but now that I've got one, it's getting a LOT of use.

good question. and the answer is: im flat broke. all i have to work with now is $30-$35. I figure $20 to get the spores here, and than the rest goes toward the brown rice flour and the vermiculite. so that doesn't leave me any money to buy a pc for a loooooong time
Edit: I just read that if you use a jar bigger than a 1/2 pint on the pf tek, it wont work. as you can see I don't have much spare money for the jars (I don't think) so I have two questions: 1. can I use a larger jar (1 pint I think) and 2. how much would like 2 or 3 1/2 pint jars set me back?

im not sure if you can buy one or two jars. just use a glass fill up with brf/verm substrate. then put the dry layer of verm on top then put some plastic wrap over that. poke a 4 or so pin hones in the wrap. then put tin foil over that. boil in pot for an hour or so. then let sit till cool. if u have no money get fsrc spores. they are 2 bucks but you are expected to donate prints back once you make them. its a community thing which is neater then people selling shit for profit. anyhoo ive boil/steamed my pf jars and it works. but save up for a PC beucase once you have sucess your going to want to keep growing.
oh an you used the term casing incorecctly up there somewhere. casing is an option AFTER you have colonized jars. good luck!
oh and you can use fractional sterilization for grains but its an effing pain in the ass. i thoguht screw buying a pc cause i had no money but once i tryed grains and it worked i needed that pc more then books. so i went without my english text. goood call too!

the cheapest way to sterilize them is to get a loan of a PC off a mate or a mates mate people wont think your growing mushies just say your cooking something ... apart from that i used a steamer for many sucessful grows, or check about microwave teks use the search make sure you change the date on the search to 10 years ... but seriously the cheapest way to do anything is to either get a loan of stuff or buy it keep the reciepts clean them well then return them or since blokes dont like returning stuff just get a girl friend to return it .. they love it haha

Now before you go spending all your money.. a few things to consider.
You need to incubate them as well. You can incubate your jars at room temperature, but it will take a long time. A much better method is TiT (Tub in Tub Incubator).
Also, you are going to need to make a fruiting chamber. Do a search for PmP (Poor man's pod). This is going to cost a few bucks too.
When you are boiling, be sure to really watch the pots. Keep adding water as necessary, because it will evaporate very quickly, and the bottom of the jars will burn.
Good luck

Yes a PC is probably the best resort but if you dont have the money for then you can always go the route that I went and just steam the jars.I used the same method as you (verm. brown rice.) I steamed my jars one at a time though, which i personally think helped.Youre gonna need a tight fitting lid though to work well or it will take much longer to steam.My first jar i didnt have a tight fitting lid so i sterilized for about an hour and fourty five minutes which seems to long but it worked just fine. My next few jars i got a better fitting lid and only sterilized for an hour. I was using a b+ to inoculate them and from what everyone is telling me there doing just fine and it wont be long till they'll be growing. Good luck to you and hopefully i could help. Shroom
