newb sterilization help

this is my second attempt at growing. The first time failed due to some stupid mistakes i made , being over anxious. Anyhow. This time i made my own 1/2 pint jars instead of purchasing them. I followed the pf tek directions exactly. 1/4 cup brown rice flour , 1/2 cup vermiculite , 60cc of water and a dry protective vermiculite layer at the top. now im ready to sterilize. i dont have a pressure cooker. I have an oven though. Could i use that to sterilize if i cooked the jars in there around 200 degrees for a while? has anyone ever used this method before? How many degrees and for how long should i do it? Are there any other recomendations other than using a pressure cooker? Input will be very much appreciated. Thanks a lot.

You can just cook in a big pot on the stove. Make sure you put a cloth towel on the bottom of the pot so your jars don't crack. Cook your jars with the lid on the pot for 60min to 1hr and a half. I think all this is spelled out for you in the PF TEk. Read the PF Tek. Google it if you don't know what I'm talking about.

Correct. Follow the tek. You can not sterilize in the oven. If your substrate reaches 212F/100C in the oven, by definition, all moisture will have totally evaporated from within. You need to boil the jars. Be sure they are wrapped so that the water that drips back down from the lid doesn't get into the jars.
The first investment you should make in the mycological hobby is a pressure cooker. RR

use the pot and stove if you cant afford/find a good pressure cooker. I dont see the oven working at all.
If you want to be extra carefull. Boil em for 1hr. let cool for a bit. boil again for a half hour. I started doing this and my contam rates are much lower now.
