if all your pf-tek jars contaminate its the syringe. steam sterilizing brf cakes works 100% every time. buying a PC wont do any good, unless you're using it to start doing agar and grains.

The jars should be removed as soon as they're done. If they're left in the pot overnight with the foil on, the moisture content can get thrown off.
Also remember the other stuff I wrote like about light. Mushrooms don't grow well in darkness, they grow much better and faster in light.

yes, it does
no it doesn't.
steaming under a pressure of an extra 15 psi above atmospheric pressure causes water to boil at 120oC, enough to kill bacterial endospores and sterilize equipment and substrates. steam produced by regular boiling water will never reach higher than 100oC, not enough to kill the hardiest contaminants.
this is why you can't steam sterilize grains. this is some of the most basic cultivation knowledge.
if he is having contamination problems, and is only steaming his equipment with boiling water, he can fix the issue by sterilizing in a pressure cooker.

wow, that's really bad info dude.. you can steam grains for 8 hrs. that's basic knowledge. also we dont kill all endospores we knock them back enough to get a window for colonization before they're back up. also basic knowledge. https://www.shroomery.org/forums/showflat.php/Number/19217560 also, this dude is using the brf-tek. 90mins steam sterilzing works 100% of the times.

so you confirmed my statement, that steaming doesn't sterilize, it only knocks contams lower long enough for you to get a leg up on colonization. nothing i said was incorrect.
plus, if you're steaming grains for EIGHT hours, do yourself a favor and get a freaking pressure cooker.

Not even 90 minutes in the pc kills them.

i disagree. i have sterilized both solid and liquid substrates in PCs and autclaves numerous times before letting them sit for days, sometimes WEEKS, and they remain uncolonized and sterile. same goes for the biochem/microbio lab i used to work in. if they weren't sterile, they would quickly become contaminated.

no, "sterilizing" grains doesnt sterilize them. only knocks endospores back. brf has no endospores. so 90mins steam works every time.
You really shouldn't talk about "basic knowledge" if you dont even know this.

awesome. pop into cult for the first time in years and a bunch of people without any grows to their names try scramble over each other to prove someone wrong and look smart.
thanks for reminding me why i left this forum such a long time ago.
btw, you better hope those medical autoclaves do a lot more than simply pasteurize equipment if you ever need to have surgery.
good luck folks, and to the OP, use a PC, otherwise it's your syringe.

To the op: dont give up dude, this hobby is very rewarding and a lot easier than your unfortunate experience has led you to believe. I know people have been preaching at you about agar and it seems intimidating, but they're right and agar is way easier than you can imagine. Ive accomplished so much more with agar than I ever did without and overall I'm a successful and happy cultivator, sitting back and reaping in the rewards in exchange for a little time, money, and experience. Dont give up. Thats just gay

lol, we're talking about grains here not tools.. and we never mentioned pasteurization, you got the terms all mixed up. sterilizing scalpels in a PC...easy. sterilizing manure..easy. sterilizing grains with endospores.. fuckin hard.

I dont even remember the timeline but it is like 12 hours to sterilize a qt of grain in a pc.

I pc my grains for two hours and use agar and I still get bacterial issues. Nothing significant though.

Instantly judges people and has the I'm better than everyone attitude because they said he's wrong... Even worse he thinks 140-160F is the same as 212

perhaps take a quick glance at the user profiles, ratings, and main threads of these people you are disagreeing with.
