well, there's too much space between
such large particles,
too much unfiltered air getting in
sand would be better

i wonder why the peat itself doesnt fair well
is it because of low nutes? verm doesnt have any nutes at all and look how fast its flying. maybe consistancy? maybe myc likes the "taste" of verm more.

I think it is the lightness of the substrate. Also, I think a 50/50 rice/peat mix would be better because the peat "packs in" around the rice in a way verm does not.

Verm, 50/50, Peat (Hawaiian multi-spore)

Verm - all cups done or almost done (tiny patches)
50/50 - nearly done, strips and sections uncolonized.
Peat - Argh! Only about half way there.

hey hey hey now...... did u only do 2 cups? if u did alot, and none contammed, this looks pretty nice

those 99cent plastic cups stood up to steaming? damn, i think i may do thsoe from now on, i can fit more of those in a pot than my regular containers, damn!

did you just pack the brf/verm mix into the cups, then the dry barrier, then tied the tin foil to the top, steamed, and just innocced thorugh the foil? thats it?

Even if it doesn't contaminate, I see the mycleium wasting a lot of energy colonizing the peat. I would expect this to contaminate as well. As soon as the peat gets wet, trich will grow on it.

That's interesting, peat is listed as the material of choice for casing material in TMC...either as a 4 peat:1 lime flour:.5 lime grit:2-2.25 water or 2 peat : 1 chalk or marl: 1-1.25 water ratio. And here I was already to follow mr stamet's suggestions.

So increasing the alkalinity doesn't keep out contams? and the only sure fire way to keep contams out of a casing layer is to ensure that there are no nutrients in the casing layer?

Or is this extreme view of casing only needed if poor air exchange rates exist? Because don't contams thrive in high co2 which is opposite of what fruiting conditions require? (assuming they are given soething nutricious to grow on?)

the foil covers are keeping the mold spores off,
apparently.
i'm surprised but hey
that's what makes real experiments
so much better than conjecture and opinion.
but i too
would like to see more examples and further along as well.
still,
lookin' good.

I like the idea...Seems like trich usually starts on more nutritious materials then moves on to gobble everything in it's path, so if the spores cant get down to the goodies i would'nt think they would germinate . As long as the nutes in the jar dont wick up through ,then maybe it does work...That extra thick layer could b key...

is that cup a pint? or half pint?

also, just a rubber band and tin foil, would work fine? after innoculating through the tin foil, did u tape?

I predict he'll find trich when he removes the lid. The foil is also holding moisture in, therefore the peat is damp.

ah, but even if,
still the cake is nearly fully colonized
and once can just shake off the peat...
but i see no sign of any trouble in
those recent pix.
he may have just pulled this off.

is peat inert? like, does it have any nutes for trich to hatch? if not, i dont see why dry peat would be more contam prone than dry verm....

also, i think that way you're doing it seems way easier than using canning jars, plastic 99cent cups, tin foil and rubberbands, i think i m gonna do thse from now on, i can fit like 10 of these in my pot, as opposed to my 3 1 pint chinese food containers...

did you innoculate right through the foil? did u tape the hole afterwards? or just left it?
