Basic casing questions
    #3411472 - 11/26/04 10:23 AM (12 years, 5 months ago)

I've gone through all of the casing info I can find on this site and others and I have a couple of questions.

When using the aluminum baking pans whats the best way to sterilize those before adding my casing? Lysol, bleach, alcohol, oven?

When applying a substrate (colonized popcorn) to a casing mix (6-/40 coco-coir/verm). How deep should the bottom casing layer be if I'm planning on a 2 inch layer of substrate. Then for the covering layer - how deep should that be?

Does the aluminum foil I'm using to cover the pans need to be sterilized as well?
Thanks a ton!

Do you mean "SUBSTRATE"? Assuming so.... use 70% alc swab on container.

I'm not a fan of aluminum pans. They are FLIMSY, bend easy & the acid an older cased substrate emits will eat holes in them.

A substrate should be as large (deep) as possible (example = 6 inch deep pan = 5 inches of substrate).

In example above 3/4 to one inch of casing layer works well. Be sure PH of casing layer is correct. Otherwise, whole pan will go to shit :mad2:

I just use lysol to sterilize my casing containers.  Wipe it down real well.

When you are applying substrate, just use a quarter inch or half inch bottom layer (depending on the depth of your pan), because you still want enough room for atleast a 1 1/2" thick substrate layer, I'd go with 2" as it seems optimal.  And then a 1/4" casing layer at the top.  Some people say make it 1/4 your substrate layer, and that would be a 1/2" thick casing layer.

So to sum that up:

Bottom Layer: 1/4" to 1/2"
Substrate: 1 1/2" to 2"
Casing Layer: 1/4" to 1/2"


As far as sterilizing your foil to cover them with, that's probably more of a personal opinion.  I sterilize mine.


Tip:  Be sure to cover your whole substrate evenly with your casing layer because light can reflect off the sides in an aluminium casing container and will cause it to pin down there, the pins will rot without you knowing their down there and then cause contams.

Anyway, good luck Brian! :thumbup:

I disagree, unless you're using poop or something.

If you have a 4" substrate layer, you're cutting down on the surface area that will be pinning and producing mushrooms.

Mushrooms seem to grow the biggest and in most quantity with 2" substrate layers. Anything more and you're wasting substrate that could cased and producing mushrooms.

The advantage to having a 5" substrate layer would only be that it could possibly give off more flushes so long as contams hold back.

Grin.... we all go with what we know. You know what works -best- for you & I can't argue with that.

This I know. Commercial mushroom beds average 8 to 10 inches deep.

About 150 years of trying differing bed depths went into that finding.

I use compost substrate (same as Commercial Growers do). I do so because that same 150 years of testing - prove it is the most productive substrate.

Deep - large substrate - well cased - in optimum enviro's get you shrooms like this.


They also flush more times & are easier to add water to.

4th or 5th flush (I forget which). :thumbup:

Agar - are those just basic plastic potters you're using?

No........

Those are used black plastic tubs that underwater pond plants were shipped in. I just stumbled into a pick/up truck load of them - behind a shed - one day - shopping at a "pond" supply place. I asked the manager what he wanted for them & said $20. I started loading my truck.

But.... hey..... about anything (light will not shine through) works - just go with whatever is cheap, fits in your outfit & easy to find.

Excellent. Just wondering also if anybody here uses the Gro-Brick brand of coco-coir?

One thing is for sure, my substrate depth will be increasing. :thumbup: :grin:

Where do you get gro-brick? Foaf uses bed-a-beast from the petstores.

wow 5in of substrate. with just popcorn isn't that a bit thick i though that anything over 2 was a waste?

and commercial growers don't usually grow cubes do they?

Substrate depth depends on substrate type. Like agar said compost subs are the best yielding but if your using grains then IME 1.5-2in. depth is best as Silven said surface area will be most cost/effort effective. agar you speak wise words indeed reminds me of an old friend and colleague I once knew. :wink: Welcome aboard!

Agar I think you're speaking of bulk substrates when your talking over 4" thick casings. I've tried whole grains in many incrimendts from 3/4" up to 4 1/2-5 inches and I've found that It's better to have 2 pans the same size 2 inches thick then 1 pan 4 inches thick. I stick with about 1.5-2 inches now..I could put more in but then its just more work for not so many mushrooms. When I work with straw though I definitely go for 6-8 inches. All this is just me though, maybe others will find different -shrug-

Reguardless this person already said they plan a 2 inch thick substrate layer and just want to know how thick to make the bottom layer of casing. You only need 1/4-3/4" if you want it but you dont really need a bottom casing layer..I'd just put 3/4" casing on the top of the substrate myself. Aluminum pans do make pretty crappy casing containers..almost impossible to reuse to..I'd suggest a layer of foil underneath then wiping that down with alcohol..I've had myc eat through the bottom of my tin pans.. Then until its fruiting try not to move it at all and even aften be carful moving it or you'll create some earthquakes and fault lines.
