Using a pot instead of a pressure cooker

What is this absolute reticence for using the tool of the trade? Yes, you may be able to sterilize a finely granulated substrate using boiling water or steam. But you will have more and more trouble as your elevation increases.

Many microorganisms produce endoscope. The natural purpose of endoscope is to resist environmental extremes.

Boiling water may kill 99.99 percent of all endoscope after an hour or so.

But it only takes a single survivor and there may be billions of spores in your substrate. Wet heat, and wet heat under pressure not only speeds up the process but invades the micro crevices in the substrate.

I can't believe I'm saying this, but yes, if you take care to prompt the endospores into germination first, by ensuring the substrate is moist and kept in the low eighties for 12 to 24 hours, you may be able to kill all contaminants in a grain medium by boiling after the spores germinate.


Several hours boiling may do it. If you insist. Set up your substrate, wait for a day but not so long as to let your substrate sour thus changing the pH, then boil, then let it cool and boil yet again, you will most likely arrive at a sterile substrate.


Or, you can get a pressure cooker and make your life, far easier.


Those pressure cookers will also cook artichokes to perfection.
 
Look bro you have to have a PC if you want 95% success rate but don't be discouraged by the pressure cook users you can still do quite fine with just steam sterilization but you have to at least havit sterilizing for 2 hours depending on substrate I would use wild bird seed the kind with no sunflower seeds whatsoever make sure you rinse them really good in cold water. Cook the bird seed first in water let it simmer for about 30 minutes until you see the seed start to pop open strain it and rinse really good with distilled water only let dry for 15-20 minutes maybe more if it's still too wet. load it in your jars without closing it all the way wrap the top with tin foil and steam for no less then 2 hours now this is the important part when you're letting it cool while it's still hot but cool enough to touch duct tape the whole top of it until it cools overnight then you want to cut the tape off immediately tighten your jar lids keep the foil on them and take them straight to your glove box knock them up and when you're done spray the top of the jar with rubbing alcohol if you're using RTV silicone put your tinfoil back over them and make sure you put them jars in a plastic container with a lid every few days spray a tiny amount of Lysol in the container do not open this container unless spraying Lysol in it 30 days when the 30 days is up pull everything out and check it if it was all done right almost every single jar should be fully colonized with no contamination just make sure you use distilled water in everything you do except for rinsing the bird seed before the cooking process. It's a lot to do but it will work.
