100% Guaranteed Casing Tek

Take enough moistened and pH buffered 50/50+ mix(peat/verm/oyster flour), to cover your substrate to a depth of 1/2 inch MAXIMUM, try to stay closer to 1/4 inch. Use a reliable pH testing method to test the pH of EVERY batch, don't assume that because the last batch was a perfect pH of 8 that every one is, they will vary quite a bit.
Use oyster shell flour to buffer the peat by adding 10% by volume of dry oyster flour to dry peat. Mix your dry oyster flour and dry peat together before hydrating. Achieve a pH as close to 8 without going over as you can, if you have to use more oyster flour do so, but give the flour a few hours to do it's magic before adding more than 10%.
Practice good pasteurization teks before adding casing to sub.
Cover your substrate layer with 1/2 inch maximum of the moistened and pH buffered 50/50+, and incubate in an ideal temperature of around 75 degrees, although temps as low as 65 degrees are fine if you are patient.
Once 20-30% of the the casing layer has colonized (7-15 days) it is ready to be placed into a fruiting chamber.

nothing is wrong with this tek.
well, a couple misguided ideas imo, but nothing 'wrong' at all.
first, oyster shells are a long term soil buffer not really suitable for casing layers, as the average casing layers life span on a substrate is about 3 weeks. oyster shell breaks down and buffers at a very very slow rate, months and months...now if you were to use oyster shell flour instead....theres your short term up front good calcium buffer that wont burn your mycelium. nothing wrong with this, as it'll actually work just fine without any ph buffer whatsoever, with just peat and verm. as far as ive learned, the only purpose of ph buffer is to exclude competitor molds for our favored fungus. another personal favorite of mine is calcium carbonate sand, mixed in at a rate of about 5-10% of verm/peat, when oyster shell flour isnt available.
secondly, its not actually recommended to incubate a tray thats colonizing the casing layer at 80 degrees, it'll do just fine at room temperature. nothing wrong with this, just not required, and if you're actually incubating something, shouldnt it be jars and grain and such?
also, most people fruit at about 25-50% with even breakthrough. once again, nothing wrong with this at all, and in fact this can vary greatly due to strain, growing conditions, or personal mycologist preference. some strains can be fruited at 25% and they'll continue for another 25% until stopping. the only reason i suggest fruiting earlier than 100% or even 75% colonization of casing layer is because the more colonized the casing layer is, the less water the casing layer can absorb.
thats my personal input, other than that, its a fine casing tek.

I just had a few questions about your tek...
When you say colonized substrate, are you talking about BRF cakes?
You say adjust with crushed oyster shell. Isnt hydrated lime used to raise your PH and crushed oyster shell maintains it?
Why cant you harvest the initial fruits and let the rest of the casing finish together? Does this harm the substrate?

1. -substrates should not be held under 2 inches! an optimal cube substrate is 3-5 inches deep.
2. -jiffy mix is no longer available at over 75% of Wal-Mart's. -the uncomposted woody material should be removed from it. -crushed oyster shells will NOT adjust pH, they'll just buffer it. -casing mix should be pasteurized, not just used as is
5. -normally a cased substrate is fruited immediately or at first sign of myc. poking through the casing. not after the casing has almost fully colonized. -you should NEVER harvest healthy pins (primordia) before they have had their chance to grow. leave them be and they'll grow on the next flush. picking them just hurts your overall yield. -misting with hydrogen peroxide is a huge mistake. it only severely harms the mycelium, it helps nothing at all.
don't get all pissy. you asked, I told. take it as constructive criticism... please.

It can be BRF or colonized grain, either one, but most recommend Rye.
Hydrated lime works of course, and I did mean flour, not sure why I typed crushed, I think I have only seen flour, and there seems to be a larger kind.
You can harvest initial fruits, it's just a matter of convenience.

I was under the impression that you start to fruit right when you see myc growing in "the hills and valleys" of the casing, waiting till 75% would cause overlay right?

no, overlay is a special condition of excessive watering/exposure and panning or 'dying' mycelium, causing a non-responsive mycelial mat on top of your substrate.
a tray at 100% colonization of casing layer will still fruit and isnt considered 'overlay'.
in fact, most people wont ever encounter overlay, unless they really really try to =)

I'm gonna rez this thread...hope no one gets mad, I just couldn't find the exact question I needed answering after sifting through hundreds of posts.
Popular technique indicates that you should fruit when you see myc popping up through your casing. If this technique is followed step by step but full pinset and flush is lacking, perhaps someone could locate an error that is being missed.
Conditions: - 55qt DT using polyfil (6 small holes drilled instead of 4) - 2" substrate (Myco's compost/coir/coffee mix)
**It should be noted that the entire substrate colonized extremely fast, approx. 6 days**
- 50/50 casing at 3/4" depth (with oyster shell & lime)
**Immediate myc popped through(small spots) at the 3 day mark, and since then, almost nothing. Day 5 came and the DT was exposed to fruiting conditions. The moisture in the tub seems a bit low looking at the casing but there is still water droplets all over the walls and top. The RH in the fruiting room ranges between 5-10%. It's now the day 6 of fruiting and barely anything has changed since day 3 of incubating.**
Cleanly techniques were followed zealously, quality ingredients are used fresh, and very close attention to detail is paid to every aspect.
HELP!!!!
