Mason jar in a pressure cooker sounds like a good way to blow yourself up...
Exactly, you have no experience in the area. So why would you tell me what I suggested would blow up? You sterilize mushroom spores in mason jars in a pressure cooker. There’s multiple recipes showing how to decarb in a pressure cooker. It’s actually one of the easiest ways.
autoclave
thanks for the link. interesting results. i'm wondering why there was so much variance in total THC content though. but it's a good reference point
Idk
With mushrooms you have tiny holes in the lid that are used to innoculate the jar. Those holes allow pressure to escape. If you put a jar thats sealed in a pressure cooker it will blow up if there is any moisture content inside.
Ya...people have been using pressure cookers for canning for hundreds of years.mason jars do not blow up in a pressure cooker
actually, the temperature is directly related to the pressure. you can look up a chart for the temp that water boils at under certain pressures. 10psi, water boils at 240 deg (which is the oven temp most suggest). that's why i wanted to experiment with using the pressure cooker. it's more stable than an oven, because you set the rocker weight to the pressure you want inside the pot. once you get the pressure stable, it's just a factor of time after that!
So you can hear the water boil? Or you just heat it to a certain pressure...and trust that your guage is accurate...
you know the water is boiling by steam exiting the port on the lid of the cooker. make sure your cooker comes with a weighted rocker that has 5, 10, and 15 PSI specified on it (on the right side of the lid in the pic). the weight of the rocker is calibrated to the actual cooker to maintain that pressure. after you see steam flowing heavily from the port, place the rocker on it with the desired psi lined up with the steam port. then adjust your heat accordingly to maintain a steady pressure. the lid also contains a pressure gauge that will tell you where you are at pressure wise (left side of lid).
I own a Wolfgang Puk Pressure Oven and it works amazingly well. If you have a vacuum sealer and those heavy-duty .5ml bags or whatever you can find in the store that is food grade and can withstand the heat. So what I do, is put whatever cheap oil i can find that has a high smoking point and find a large square pan that’s about 3” deep. Fill with oil and place into the oven @ 250* f. You do not need to ‘Pressure Cook’ the oil, just get it up to temperature.. then place whatever amount you have into the bag, get it spread as evenly as possible (just make sure there are no large lumps of your plant material) vacuum seal until all air is pulled out. Pull out the oil that is up to temp, place bag into the oil bath (you might need a metal spoon or something to hold it under the surface of the oil decarb for 25-30min, pull everything out, then pour your oil of choice that you’re infusing into a new container, wait until your herb has cooled to room temp, and pour in the oil you want to infuse, not the oil you used to decarb the bag of weed in, but let’s say coconut oil. (Melted). Then what I do is pressure cook that mixture at 205 for about 2-4 hours in a water bath. (Same method as before, but substitute the oil with water. You may have to add water periodically, but not much...). So you’re infusing your oil in a bag but not vacuumed.. I haven’t tried just putting it into the oil to start, this was a friends method and I haven’t strayed too far from the method...
yeah i understand that. i work with pressure cookers a lot in the mushroom business, they're not hard to keep at pressure if you watch them closely for the first 5 minutes.
right on. you're not "pressure cooking" anything at 205 though fyi. have you had lab analysis done for your method? do you know how effective it is? I'm a data kind of guy...
