Pasteurising coir in cooker without thermometer..?
    #23965481 - 12/29/16 12:52 PM (7 years, 1 month ago)

Hi there,

I just wanted to know if it was possible to pasteurise coir/verm mix jars in a cooker with lid without having a meat thermometer..? I have a digital laser scanner thermometer but it would mean having to take off the cooker lid and scan the foil at the top of the jars.. Is there a way to do this without using a meat thermometer or bucket tek - as mixture is loaded into the jars already. Is there a preferred temperature I should turn up on the stove and time I should leave it to boil for..?

Any advice is appreciated :-)

Not neccessary but it works. Sometimes I PC coirwith grain jars.
I would heat coir because some brands seem to make their bricks in another way than other brands. A 15 min PC run would kill mold spores and this is what you want.

You can take the lid off while your pasteurizing to take the temp with the laser scanner.  I just dont know how reliable that will be im not familiar with laser temp guages

It will probably give an accurate reading of the foil or glass temperature but not the centre of the substrate in the jar :undecided:

you need to know the heat at the center of your substrate mass not the outside of a jar.

Only benefit to proper pastureization of coir is practice for when you need to pasturize something that actually requires it like manure/straw/peat ect.

Coir dosen't require proper pastureization, PC it, pour boiling water over it in a bucket, hydrate it with tap water, whatever. No need to monitor temps no beneficial microbes to preserve.

You know really when it comes down to it.  If your going to go beyond pf tek then you are going to need to learn how to properly pasteurize.  Your telling ppl to bucket tek which breeds laziness which is a really bad condition to have growing shrooms.  Start cutting corners w pasteurization what other corners are you going to cut?

It's not cutting corners with CVG, there are NO benefitial microbes to preserve by monitoring temps:shrug:

why do so many advise on not PC coir as it kills microbes needed to fight contaminants and other reasons ... ?

Thats the difference between past and sterilization.  Pasteurization kills all the bad bacteria while keeping all the beneficial bacteria.  Sterilization kills everything

Ive never heard anyone advise not to PC coir, maybe in some really old threads. Some people prefer it saying it further breaks it down making it more easily consumed by the myc.
