I fucked up pasteurisation, what do
    #23384289 - 06/26/16 02:17 PM (7 years, 7 months ago)

I have been following Frank's TEK to proper pastuerization. This was my first time using hpoo. I hydrated it and mixed with coir, vermiculite and gypsum

Core temp before pasteurisation was 84F. I switched off the heat at 150F

End of pasteurisation core temp read 175F...... and I think it's been at that temp for more than a few minutes

My question is can I do something with the substrate, can I let it dry and than re-hydrate and try to pasteurise it again? or is it just totally useless? :shrug:

No, you can't re-pasteurize. Next time switch off the heat sooner though, like at 130º or so.

However it may be just fine to use.

I was thinking of just using it and see if I'll fluke it :shrug: Got nothing much to loose really

I don't have anything else to use it for

Once it cools back down he could probably mix in a little more hpoo to reintroduce the beneficial microbes and pasteurize again. :shrug:

You should be alright man. I'm not gonna say for sure. But I have had Pasteurizing hpoo/coir/Verm mix get up to 180 and still had phenomenal results.

It's probably fine. I overheated a batch or two when I was getting used to using an electric stove top and didn't have any trouble. I wonder if it would be beneficial to let your jars sit covered for a day or two to give the bacteria that survived time to recover.

Funny story...

I tried pasteurization on a element with a thermometer only to have it boil over...my entire place smelt like a giant fart....

I just bring the water to a rapid boil and submerge the bulk in a container....it will maintain 160-170f for 90 minutes without the hassle of adjusting the temperature and possibly exceeding safe temperatures....not a issue with coir, it is with horse manure/straw/compost based bulk....

I think my mistake was turning the heating back on, for around 5mins, during the last 20minutes of the pasteurisation process. I don't have any hpoo left, this was my only bag. I usually do CVG but I wanted to try something different

I should be spawning to bulk today as I left the bags cooling over night

will post results of the tub

If it helps I've done this plenty and still had fruits come out of it. Once I got the internal temp up to 190 and still had some trays. It's shitty it smells burnt though, and I did see more trichy trays when I did overcook it.

Question;

Is it possible to use the left over as a casing for my other mono?

Its pushing up fruits and I can see the mycelium is eating it's way through the verm casing
