0 minutes at 15 PSI. Coir (or any bulk substrate) should never be sterilized. Pasteurize for an hour a 140-160F.

50/50 coir to verm.

i see no problem with that but i also don't see those numbers in any given teks, even coir for casing there should be more verm then coir and for bulk most prefer about 70/30 coir to verm

How long at 15psi?

Do I need holes in the lid or can I PC with lids as is?

So how many successful runs with sterilized coir/verm does one have to do before the contams you claim will show up make their apperance? I'm closing in on 60 successful tub/trays and the 3 that contamed were all traced back to dirty spawn (one bad syringe,  serves me right for shortcuts, two plates that I was not careful enough in observing and the mold was spotted after the fact).

No need to respond the question was rhetorical

I have talked to quite a few people about their experiences with it and while we probably fall short of the thousands of subs you require,  I'm starting to think the only person it doesn't work for is you.

Your aspergillus issues aside, lets look at how pasteurization works. Thermophyllic bacteria survive the process and fight off the competitor organisims.

Lets have a look at coir now.

Is there any bacteria present in the dried, heat pressed brick

No

The end.

Pastywhyte said:

Yeah cause most bacteria can survive the 850 C temps that its pressed at I have also heard bacteria does real well in a zero moisture environment

Fine. Assuming that the bacteria on the outside of the brick made it into the centre of the jar to survive the pasteurization process, I have never seen coir mold on its own. My snakes hidebox, at this very minute, is full of moist, sterilized coir. He has been pissing and shitting in it for weeks. No mold.

I did a bucket tek a loooong time ago. Sneezed into the bucket when I opened it, and took a handful out, in open air, tossed it in a ziploc bag to save just in case (I was a noob, thought I might need to patch my divots or something) years later and no contams present. It finally dried out in the bag. No mold.

A buddy of mine did a bucket tek, opened it a few times to use some of it, sealed back up, and left for a few weeks. Came back and no mold.

A cultivator on the boards did a test with coir that was pasteurized, bucket tekked, and sterilized, then left in totes for a long time. No mold.

I could list off many TC's that either swear by the bucket or sterilized coir. I have seen side by sides of sterilized coir vs poo to see how fast the poo contamed, while the coir kept going. Many other people other than myself have used it with success. I could (and already have) post 2 dozen links. You must just be special

Fact is that substrates which require proper pasteurization, will all do the same thing if sterilized then spawned in open air. Mold +95% of the time. I don't care if your talking straw or poo its the same, every time. Why then can someone get away with sterilized coir 60 times but, in your opinion they just haven't run it enough and the end is coming. Ridiculous.

I have a theory that people who blame the bucket or sterilization for their trich issue were just starting out, and those options were attractive and simpler than proper pasteurization. But their spawn was crap and when the subs triched out, people like you told them "bucket tek is bad". So they switched to proper pasteurization. In the meantime, they got better at spawn making, put two and two together, deciding buckets or sterilization = trich.

These myths are terrible IMO because they distract from the real issue, making clean spawn. Since everyone is defensive about this aspect of the hobby for some reason, and so if they can blame the bucket they will. In the meantime the disinformation abounds and many fail to focus on their spawn and sterile tek. Got trich, oh my temps got too high Bullshit, its the crappy tyvek filters or their open air G2G, or reliance on syringes. But because there is an easy whippy boy in the room, these real vectors go unnoticed. Misinfo FTW

Anyway my last couple tubs have been done with the bucket because its easier. But one thing I have noticed about sterilized coir is that it seems to deliver more yield in the initial flushes and will be spent sooner. Same total yield, but in fewer flushes. I am planning an experiment soon with it. I await your ill informed flames.

Anyway kids I'm off my soapbox, just remember, if your gonna blame the bucket, or sterilization for the fail of your CVG substrate, do me a favor and step up your lids, inoculate, and SAB work too. I'm out.
