Conflicting information on casing
    #4515429 - 08/09/05 08:27 PM (12 years, 1 month ago)

My PF jars are near complete colonization. Once they are finished I plan to case them but I'm finding conflicting information and would like some help clearing it up.

1. What ratio of colonized substrate vs casing material do I use? When I read the 50/50 tek it tells me to use 1/2" to 3/4" or even up to 1" casing material and 2" - 3" colonized substrate. This conflicts from what the FAQ and the TMC says in this post http://www.shroomery.org/index/par/23441. What ratio should I use?

2. Should I use the 1/2" wet verm at the bottom, it seems like a good idea.

3. What mixture of peat moss, verm, oyster shell, and lime should I use? I like the 50/50 tek because it has exact measurements but it seems to be 2nd guessing itself. I bought a PH meter to work the casing myself but the stupid thing didn't register properly. I don't have enough $ to go buy a bad ass one so i'm stuck relying on someone else's formula. If anyone has a formula that they were able to reach 7.5 PH and tested it, I would be very happy to hear how you did it.

4. How long do you let the mycelium grow before initiating pinning? Most of the teks say 2 - 3 days without touching it. The 50/50 tek says to wait 1 - 2 weeks. I figured I would be asking for a good overlay if I waited that long. I need some clarification.

5. One last thing, a bit off topic but how do you know when the PF jar is completely colonized? How long should I wait after the whole jar is white?

Sorry for the barrage of questions but I've read a ton of stuff and these are the ones that don't make sense. Thanks for your help!

1. Casing layer should be 1/4 of your substrate layer

2. I don't use verm on the bottom as it creates a haven for contams

3. 50/50+ tek tells you exactly how much of everything to use, break it down into percentages if you have to

4. I throw my casing right into the fruiting chamber after putting it together, some like to let it incubate for 2-3 days before going into chamber.

5. After the entire jar is white, give it another 3-5 days to fully colonize the inside.

OfflinekronnyQ, on question 1 you say you use 1/4" of 50/50 mix and how much of the colonized mycelium?

No not 1/4", 1/4 of your substrate depth. So if your substrate depth is 4", use a 1" casing layer.

thank you for this post. It has made me want to attempt a REAL casing instead of my ghetto ones:

now all i need is a good "formula" for a casing layer. all i have is verm and peat moss (with no buffer) laying around at the moment.

Just don't go over 1" and I'll always recommend less because IME that much is not only necessary but wastes time and the myc's energy IMHO. I recommend 3/8-5/8" no matter what the substrates depth although a 6" substrate will benefit from a 3/4" casing. Read this and you will have a better idea of whats what: Getting the most out of your casings!, A pinning strategy.

Thanks for the link to that post it helps. Alright, couple of other questions.

1. Do you guys use agricultural hydrated lime or calcium carbonate?

2. This will make me sound stupid but I'm trying to get the terminology right. When you say "No not 1/4", 1/4 of your substrate depth. So if your substrate depth is 4", use a 1" casing layer." You mean the total depth of the casing (which I assume means my 50/50+ layer and the colonized mycelium) is 4" where 1" is my colonized mycelium and 3" is my 50/50+ layer. Do I have it right now???? When you say casing layer I would assume it means the 50/50+ but I guess that's referring to the colonized mycelium. Sorry for the noob question but I'm just making sure that I understand.

Also, hyphaeModerator says not to go over 1". I'm assuming you mean 1" colonized mycelium. This means you would have 3" of 50/50+ on top of the 1" mycelium. Then you say to use less because using 1" makes it have to work harder. That doesn't make sense because the more mycelium under the casing layer (50/50+ layer) would help it grow faster (I think). Could you please clarify for the simple minded (me :P) .... Thanks again guys.

1. Use calcium carbonate, not hydrated lime. They are not the same. http://www.lime.org/faqs.html

2. Lets say you crumble up all your PF jars and put them in a tray. Lets say the total depth of your crumbled cakes is 3 inches. Put one inch or so of casing mix on top of that. Then wait for the casing mix to fully colonize, then initiate pinning.

#1 Working with peat based casing mixes you'll want to use a bit of hydrated lime (short term buffer) as well as a long term buffer (limestone flour, chalk. etc;).
#2 just use a casing mix thickness of 3/8-5/8th's and you'll be golden. Sounds like there is definitely some confusion which needs to be cleared up. Example: 4" of colonized substrate will require 3/4-1" of casing mix on top of the colonized substrate. 2" of colonized substrate requires 3/8th's to 5/8ths covering of casing mix, now mind you this is my personal preference and will work awesome for everyone else as well.

Ahhh, right on, I had it backwards.  I thought I should have more 50/50+ casing mix than the colonized substrate.  Thanks for clearing that up for me.  Wish me luck :smile:  I'll post pics when they start growing.

I have oyster shells, I just need to get ahold of some calcium carbonate.

hyphae, do you use hydrated lime or calcium carbonate in your 50/50+ mix? Also, do you do the 1/2" wet verm as a bottom layer?

I use both, a good casing mix contains both a short term buffer (hydrated lime) and a long term buffer ( calcium carbonate, oystershell, etc;). The bottom layer has gotten lots of misinformation, it was suppose to be semi-dry layer that would absorb excess moisture from over watering. Understand a wet layer underneath is not able to transpire this can result in anerobic bacterial infection. GL guys
