You can't do any better for the buck than the Wagner. Ebay has several. I bought one for $20 or so. It was reconditioned from the factory as well.

I was wondering since you have the probe through the lid it has to stay in the 55 gallon drum right or do you drill a hole big enough to take it out and put back in?

Does the sub get saturated from the steam?
Thanks.

Another question.
If you place the probe in the middle of the sub bag,
by the time that gets up to temp, wont the outside layers be too hot?

you put the probe in the jar. i make sure to seal the jar if the probe gets wet then you have to buy a new one.

after some research and development I have found the ranco to be totally unecesary with my posted method. It works totally perfect unchecked as in my write up or with a ranco added! Good luck all.

Also, when/if you use a ranco remember to slide the probe through the lid ring before siliconing it to the flat lid part if you use a metal lid, lol.

If you have the probe in the middle of the substrate the steam will shut off when the temp gets above your set threshold. The outside of the substrate will be a bit hotter and it is possible that the beneficials near the outside of the substate have been killed, but as long as the center doesn't get to hot the remaining beneficials will take off and colonize the rest of the substrate as it cools down.

Note that this is a much better scenario then the center not getting hot enough and the bad guys surviving the pasteurization process.

Does the sub get saturated from the steam?


This is what I want to know. Sandman?

No not at all. The steam does not saturate the sub.

I guess I should have rephrased ripple's question to make it clearer.

Does the steam have trouble penetrating to the center of the substrate?

Nope, my posted method works 100%! There is no problem with steam penetration. Burlap is very pourus, and they bags are spaced evenly with space in between. There is mucho penetration, just the way I like it.

Awesome. I have looking for a good method for pasteurizing vast quantities of substrate.

I just recently found a source that will hook me up with as much as a truckload of hardwood chips per week. I am planning on growing a shit ton of King Trumpets, Lions Mane, & Pearl Oysters. Possibly shittakes too, but those are so easy to get at the store. The used substrate will be used to fertilize an organic garden effort.

Any recommendations for wood loving yummies that I am overlooking?

Blessings,

I got 3 of those Wagner steamers for free by writing the company and representing myself as a youth group counsler who wanted to show these kids about growing Oyster mushrooms.

However, even though I tried many times to use this method with a 5 gallon plastic bucket, it got to 200 degrees way too quick, so this 55 gallon method may work better. And while I tried shifting the lid to allow more and more air flow, I just couldn't keep it below 170.

I believe I once read something on this site several years ago concerning the usage of a 55 gallon drum, but I simply don't have the space to try that method. Of course, my CSI like roommate that I acquired two years ago doesn't help matters either.

If things change around my household, which I don't see anytime soon, I might re-consider your 55 gallon method.

Maybe you could work on perfecting the 55 gallon drum (or metal trashcan) method with those kids you're going to be teaching mycology to...

Sorry I didnt get back to this thread sooner. Ive been away.
I was refering to the moisture content that the sub would end up with,
But you guys have answered everything.
Thank you guys very much.

I'm going to start redoing this tek for a proper version tomorrow. We will be using spawn bags in lieu of burlap bags and it will be a complete tek start to finish instead of just a pasteurizing tek!
