I don’t really know much about fungal spores but I do know a little but about bacterial spores so if fungal spores have a comparable level of protection as bacterial spores I also have doubts that simply microwaving would kill the spores.
Heating the water to boiling at approx. 100 Deg C may kill the live and active ones but the point of a bacterial spore is to protect the “oogie” during less than optimal conditions (such as getting processes into a dried wad of a peat w/o moisture). I know the way they test autoclaves is by running a cycle with the spores of a particular bacteria in the machine, if the spores are killed your autoclave is functioning properly. If the autoclave is not working and doesn’t hit high enough temperatures AND pressure then the spores will still live because those spores are only killed by the highest temps.
Like I said, I don’t know if fungus spores are as tenacious as some bacterial spores, but seeing as smuggling a tray of peat pots under your shirt into a lab or somewhere with an autoclave and “borrowing” the machine for a while may not be the best idea I would agree with trying to find a different brand that doesn’t come with all the “Bonus! Now with MORE Fungal Spores!” or something because I would be really annoyed if my seeds kept getting attacked before they even had a chance for me to kill them myself. THAT IS MY JOB and I don’t need no fungus beating me to the punch…
Fungus?...I don’t need no stinkin’ fungus…..
Just get a pressure cooker. People use them for cooking all the time.
Of course you could always buy peat and use pots like the rest of us
The only thing is spores are resistant to heat, and not sure how hot the microwave gets, but needs to be at least 270 degrees. That is what we use to sterilizes spores in the OR. Of course we use pressure to get to that tempo too. Not an easy thing to kill spores.
Yeah, I microwaved the pellets wet.
They got quite toasty too. (very warm)
So, I'm going to try the little 1½" square peat-pots and fill them with my own mix in order to get some good germination.
Still gonna use the microwave and anti-fungal spray to fight damp-off...
