necessity of pressure cooker
    #22406912 - 10/20/15 12:38 AM (8 years, 3 months ago)

Just wondering how necessary a pressure cooker is when sterilizing the cakes, if I would cook longer in a normal pan with a reasonably sealing lid, how sure would I be everything is sterile ?

Don't want to waste mats, so thoughts on the necessity of a pressure cooker are welcome.

Greetings

You can steam sterilize brf cakes in the way you mentioned, but for everything else in this hobby a PC is a necessity.

You can really do a lot without a pressure cooker, including PF tek.  That's the point of PF tek, you don't need a PC.  You can spawn cakes to coir or poo and get some seriously respectable yields.

You can also do slurry and 9er tek without a PC, which gives you some basic culture and inoculation options.

Still, ain't no denying a PC is a mandatory tool if you're serious about mycology as a hoby.  If you just wanna grow some mushrooms, you don't need it.


--------------------


I spawned some popcorn casings and had double-overlay cause I didn't put enough hydrogen peroxide in my automated aquarium mister.  I only got one mushroom so I cut off the head part where the seeds fall from and put it in a jar of LC and sprayed it all over a tin of PF cakes I made with gravel, cardboard, and bisquick in my microwave.  I think it will be good cause B+ is so potent.
Triggered yet?

Only a square would say "a cube is a cube."


No, this does not look right...

you don't need a pressure cooker to pasteurize straw or i think for dung either (never tried)

pf tek, i sure as hell would use one, well except why would i be using a pf tek

but still, anything significantly nutritive and its a yes

You don't need a pc to pasteurize anything... Pasteurization for mycology is 140-160f internal temperature.

If you don't want to waste materials getting a PC is a good idea.

0 need for a PC when doing pf-cakes. the jar lids should seal nice and you should have a dry verm barrier as filter.
the seal of the pot lid is just to keep temps high.

Unless you're not in the US.  UK customers can expect to pay about $200 in total for the Presto and shipping, import duties, etc.

Which I did.  And like tetherface, it was the best $200 I spent in this hobby. :smile:

you dont really need 15 psi either, size is the most important IMO, fit more jars, just add 30-60mins cookign time if you have a lower PSI/bar PC.

In my experiments and in the wide variety of teks and substrates I have tried and developed I have learned a strong variety of different methods and materials that can be used without a pressure cooker.  Yet still pretty much everything I grow goes thru my cookers first.  So there's that, take note as you will.
