okay. this is the setup ill be usingfor the cakes:after birthing the cakes, put a down a lid and fill it with wet vermiculite. then place dry vermiculite on the top of the cake. wet that with a syringe. inject 10cc of sterile water into the cake (heard it increases yeild) . place inside terrarium with rh meter and temperature gauge. place grid over wet perlite layer for more surface area. place a little bit of h2o2 in the perlite/water mix. fan 2 times a day. give 6-8 hours of light per day.for the casing:take out the completely colonized cakes with a fork or cut up with a knive like a cucumber and place a layer (1.5 inches) of wet vermiculite on the bottom (sterilized at 160 for one hour). then place a layer of wet vermiculite (1/2 inch) on top of the pieces of the cake. leave it in a dark spot for 1-2 weeks. then leave it in a terrarium with very little perlite on the bottom to keep the humidity up. fan and mist 2 times per day. expose to 6-8 hours of light. both temps wil! l be kept at around 75 degrees.after reading reading all the availible posts, i think ill try what i said above. do you think this will work? if anything does not seem right, could you PLEASE e-mail me back at [email protected]!!!!!!!! that would be incredibly nice of you. i just tried shrooms for the 1st time about a week ago, and i loved the expirence. i paid an outrageous price for an 1/8 ($35) and would like to grow my own. i have 3 jars of the "b+" strain that are ready to be birthed. im kinda nervous since this is my first time. ive had to wait about 1 month for them to completely colonize......  your help would be incredibly appreciated. thanks.

I replied:

LOL, I usually don't help people via email... That's why I have a board, so the next guy can pick up on the tips too.

Everything you wrote sounded fine. With one exception. You were talking about casings and you mentioned covering and keeping it in the dark for a long time... a week or more. Really a properly prepared casing is ready to move into the fruiting chamber in 72 hours after it is cased up.

Otherwise, you sound good to go wink.gif

Any others? I sent him a link the thread here so he could catch any comments smile.gif

you won't need 6-8 hours of light, it won't hurt but you can only give them a few minutes of light per day and they will be fine.

also if you are doing a double end case you don't really need to inject water into the cake, it could flood the cake and introduct wet mold

Really? How deep of a layer are you talking about? I usually make mine about an inch, and incubate at a steady 82 degrees. 6-7 days is the minimum for them to be ready for me. Do you think this could be attributed to an out of range pH? Cus haven't ever tried putting any + in my 50/50. Gotta get down to a brewery store some time soon.

I use 1/2 inch of casing, and incubate at 86*F (those 4 degrees make a big difference) - 72 hours then into the fruiting chamber. They don't need to incubate any longer than is needed to get water sucking rhizomes started into the casing... And as soon as they start in, I start soaking... Three days of water and cooler temps in the fruiting chamber... Pins start in 6-7 days with early strains.

I push the timeline, but really just enough to stay ahead of the curve... And that first three days in the fruiting chamber I use to hydrate everything up as the mycelia finishes with the casing and just before the pinset.

Another way to look at it... When the casing is fully colonized, it is denser and less able to soak up and hold water. And if it overlays water delivery becomes all but impossible.

Yet another way to look at it is at 6-7 days yours are ready for mistings and then a pin set... Mine are fully hydrated and setting pins wink.gif

pH drops off further down the road a few days... But not much. Even straight peat takes a couple of weeks to "sour up" .

good advice nan....

I'm thinking of using verm+coir for casing - either OT's wafer tek or Hongus. (Is either tek better for newbies?)
Should the casing be pasteurized? If so, how? Is the best ratio verm:coir 30%:70%? I've been using 30 ml clean water per 1/2 cup verm - is that about right? Also, I was thinking a proper terrarium isn't really needed; just stick it in one of those plastic 'Maid "shoe boxes." Does that sound feasible?
I'm thinking coir is better than peat because its pH is neutral.

Sorry for so many questions - new at it. Thanks!

Yes it's an excellent mix, it does require some pH adjustment (lime/oyster shell). I sterilize in the pc, but I am just that way. You should at least pasteurize it.

I mix in water until It just beads up and drips out of my hands when squeezed in a fist, and then I soak/mist heavy once a day for the first few days to work even more moisture into the substrate.

Ratios here work from one end to the other... Pure Verm to Pure Coir, I would let the cost determine the ratios.

Ooops... There is a  Good Pasteurization Here

Dry Sterilized Casing

Fit a stiff, perforated, standoff plate in the bottom of the pc about 2 inches above the water line. Drop in a pillow case, fill with dry casing... I throw in a coffee mug to scoop the sterile casing out... fold over the pillow case, cover with a sheet of foil (to prevent excess condensation from soaking the casing mix)... I fill the PC right to the brim, slip on the cover, and blast at 15lbs for 45-90 mins.

When I go to case my rubbermaid bins I throw on some gloves, spray some lysol or rub some alcohol or dilute bleach on my hands, open the throughly cooled pc in a clean room and with the gloved hands grab the handle of the mug and scoop out dried casing.

Dried casing is easier to handle and spread. Once it is sifted into place, I use a cheap one gallon garden pump sprayer full of clean water to slowly and throughly soak it down.

The next day I soak it again.

And the day after that... By the 3rd day, it's getting wet and the mycelia is coming through... time to fan, make sure it gets light.

Very cool. Thanks, Nan.

My case im doing is going to be coir smile.gif

I got a nice big brick of coir at the pet store.

Alright, I have a bunch of old casings 3+flushes that need new casing layers. They all have loads of undeveloping pins, some rotting. Ive always just removed as much as possible and recased. Any good tips??

Posted by: Nanook Dec 07 02, 04:28 AM GMT
Clean spoon, scrape em down to the substrate while spraying with water to rinse the crap off. Make sure they are picked clean, recase.

Pure grain substrates can be dunked wink.gif

i just recased a birdseed cake i had going.

scraped the verm off, trimmed the soft or mooshy edges all the way around the cake off
rinsed off with cold water.

hoping on a decent 4th flush.

edit: just chucked the casing. forget that 4th flush.
note: next time use sterile water.

I have used a SHARPENED cement trowel. You can find them at any builders supply or hardware store for $5 or $6 bucks. I sharpen the edges like a knife. So, it will cut away aborts & all -- clean to the substrate.

Simply swab the trowel with lysol or alcohol & go for it. Once the old casing is removed, spray the surface with a mild h202 solution & recase.
