MAJOR PF TEK SNAFUS FOR THE NEWBIE
Water inflitration of the jars during sterilzation.
There have been many isolated posts concerning delayed
or stopped colonization. This seems to always concern
the lower half of the jar. The simple explanation is
water infiltration into the substrate during steaming.
This happens two ways. The first is that there is
to much water in the pot and the boiling water can
slosh into the jars. Then the water builds up in
the lower part of the jar and the soaked substrate
will not colonize correctly (or not at all - and stall)
The second way is water dripping from the top of the pot
down onto the jars. If you use regular canning lids,
these do not seal the jar and water dripping down can
go into the jars.
In the first incident - use a safe amount of water so
that sloshing into jars doesn't happen.
In the second incident - cover the lids with tin foil
to ward off dripping water.
Premature cake birth
Observe the photo of the in vitro primordiation in
the PF TEK photo files. This photo is all you need to time
the whole thing. Primordia appearing in the jar
usually starts around the begining of the 3rd week
after spore inoculation. But don't stop here. When
you see the new primordia appearing, delay birth. Doing
that influences more primordia to form. After about
3 to 4 days, birth the cake. The initial flush will
be highly influenced by how primordia form in vitro.
Newbie humidifier uncertainty.
The usuall case here is inexperience. Humidity is invisisble
and humidifiers do almost to good of a job of humidification.
The rule here is to avoid humidifiers when you are a PF TEK
newbie. The pf tek does not need the extreme high humidities
that you might think these shrooms need. A small terrarium
will produce excellently - equaling electronic
humidification (and that is no matter what the humidifier
fans say). But of course, if you want to do the humidifier technique,
the humidifier tek in the PF TEK photo files is the best because
it is the cheapest and simplest and there is no sacrifice in
effectiveness. Cool sprays are under $20 - available in the baby care
section of a decent drug store and easy to rig up.
Improper water content in the jars.
To determine the best water content, When you first do the
pf tek, make a batch of jars with the same substrate
amounts but variate the water, take notes, observe and
go with what works best.
Pint jars versus 1/2 pint jars
When I first published the PF tek papers
I included a Pint jar pf tek chapter.
And of course it was eagerly copied
(a few years later)
by the MMGG author as if it was the
cats meow (because I had dropped it
from the pf tek papers already).
In the beginning,
All the subsequent letters from the
myco customers with problems
had to do with the pint jar. It was
causing lots of trouble. 1/2 pints
seemed immune to problems.
I already knew of the pint "trouble". So I
dropped the tek. The "trouble"
was "premature" fruiting (like thats
bad?). What would happen, is that
Pint sized cakes would commonly have
the tendancy to begin putting out
primordia and screaming to be released
from in vitro BEFORE complete colonization
of the cake, mainly caused by not enough
spore solution delivered all around making
for an uneven colonization.
So there you would have a
tear jerking disaster on your hands;
primordia all dressed up with no place to go.
the cake would expose the exposed
uncolonized cake surface (which sometimes
is about half the surface) and you
will not only have shrooms growing,
but plenty of contamination (hence the
absolutely ingenious MMGG technique of branding
What is causing this is that the vermiculite
in the mixture is the fruiting catalyst which
stimulates fruiting whether the food is used
up or not. The fruiting is clearly related
to a food threshold and nothing to do with
CO2 or oxygen - temperatures ect. And this is
primordia will appear just the same in a jar
in which the lid has been on tight since
the get go. (NO OXYGEN) strange but true.
To see the truth of this in demonstration:
Try a pint jar of plain pre cooked (quite wet
and soft is the way) brown rice in
comparison to an equal pint jar of pf substrate mixture.
(you don't have to go to the trouble to do this,
but read on and trust
When a pint of plain rice is colonized,
and left to sit in vitro, Primordia will not appear
and then the jar starts to yellow - die ect.
The neglected pint jar of pf substrate will put forth
plenty of primordia hot to get it on
while in vitro.
It is like two completely different
substrate mediums but basically it
is brown rice.
In these two examples is clearly shown what
the pf tek is all about. The vermiculite
is the catalyst for fruiting - similar to
casing grain (but without the casing tek) -
sort of an internal automatic casing.
That is why all of this stuff about casing
pf cakes to make them work the best is
from people that have no idea about the
pf tek and its inner workings.
