 Doin' it without a pressure cooker 
#6943726 - 05/20/07 08:03 PM (6 years, 3 days ago) |

I was browsing over some of the pictures up in the gallery, and someone said "I'm from the old days back when we used pressure cookers", so I was curious; is there any way to go about the growing process without the use of a pressure cooker? I couldn't tell if he was just saying he was old, if he still used one out of preference even though there was another way to do it, or what, so I thought I'd ask.
I live in a small town, so it's not like I can grab a cheap one from a thrift store or anything coveniant like that, and I'm just about to start my grow. Literaly, the only thing I need now is a pressure cooker. Somewhat frustrating as you can imagine.
Any help would be appreciated. Thanks guys!

Yup, I wouldn't chance it going the microwave route. You'd be better off going with pf tek or just buying a pc.

This works but it takes alot of time!!!!!
Fractional sterilization or tyndallization is a method used to destroy bacteria and endospores in preparation of grain spawn(rye, wheat, millet, birdseed...) and agar, which requires no pressure cooker.
In this case, the jars fitted with a filter disc or a polyfill lid filter are boiled or steamed at 212°F (100°C) for 30 min in a pot with lid, three days in a row. Between the boiling steps the jars are kept warm, around 30°C(but room temperature will work too), to allow the remaining endospores to germinate.
The basic principle behind this method is that any resistant endospores will germinate after the first heating and therefore be susceptible to killing during the second and third heating.
Timetable of the tyndallization (=fractional sterilisation) process
1) Steam heating to 100 °C for 30 min
Vegetative cells are destroyed but endospores survive
2) Incubate at 30°C-37°C overnight
Most bacterial endospores germinate
3) Second heat treatment, 100 °C, 30 min
Germinated endospores are killed.
4) Second incubation at 30°C-37 °C overnight
Remaining endospores germinate
5) Third heat treatment, 100 °C, 60 min
Last remaining germinated endospores are killed

I've tried fractional sterilization twice once with WBS and another time with popcorn, both failed, I'm sure somebody could get it to work but I don't have the skills/luck to do it apparently.

I'd just order one online, buy it over ebay. You oviously have computer access. Get it delivered to your door. Get express shipping.
