How scatman does casing mix (coir)
    #4024819 - 04/07/05 04:27 AM (11 years, 11 months ago)

I'm switching to peat but preperation is similar...this is all made up though...its basic stuff, nothing new or different..but hopefully explained clearly and the pictures may help.
----------
Work in progress..let me know if you see something odd or have any questions?

Casing is the easy stuff. First thing is get everything together. Coir and verm:


Strainer (4 pieces of PVC and 4 corner PVC pieces with screen stretched across it and zip tied, leaving plenty of slack for stuff to sit):


Calcium Carbonate/Powdered oyster shells and dust mask:


Now you?re good to go. First find a bucket and throw a hunk of coir in there. It takes some time to learn the exact size to break off. I buy the huge bricks offline with huge bags of verm. The 6 cu foot bag of verm is stored elsewhere and a small bag is kept with the brick. Fill the bucket with the coir in it with HOT water out of your tap. It will help expansion by using hot water. Now just let it expand:


Now time to buffer. I put in this much, about 5-8 times:


Mixing it around very well each time. You need to make sure whatever long term buffer your using is POWDERED. Crushed will not benefit you very much as it will not break down over time. Mycelium release acidic secretions over time and flushes. Powdered oyster shells (Calcium Carbonate, chalk (not the kind a teacher uses), powder eggshells) will work to keep the pH at an even 7. Coir will perform well without the pH adjustment, however, it is WELL worth the investment. It will increase flush yield and number and decrease chance of contams (green mold thrives in acidic environment and doesn?t like neutral to well). Powdered oyster shells can be found cheap (2$/pound) here, among other places. Then into the strainer it goes and the bucket gets filled with verm up to just below the point the coir was:


Then fill with warm water. Again, warm water helps absorption. Once filled and soaked for a couple minutes, pour the bucket of wet verm into the strainer with the coir and get mixing! Usually by the time it?s thoroughly mixed (adding in verm if needed), it?s well strained. You want to use a horticultural or medium grade verm. Fine verm works, but courser verm is better. Try not to compress the verm to much at any point.


Moisture content isn?t so important because when you apply it, it can be misted to the proper content. You defiantly want it nice and moist though. It should feel like nice soil. Then you just shovel it into jars, making sure you don?t pack it down:


And PC for 30 minutes at 15 PSI. There are no nutrients in the casing mix and it should be relatively clean as it is so 30 minutes is plenty. If you are concerned, you can extend the time to 60 minutes. I have found this to make things easiest on me, I can store the jars for long periods of time until needed then crack one open when ever patching, repair, or casing needs to be done. And if you need large amounts for bulk, it can be loaded into bags instead of jars (don?t load to full and compact it, you want it to remain fluffy and airy). Make sure rubber side is up on the lid, you dont want to seal the jars and create a vacuum.

Hmmm...I've never patched in the past because i never had sterile casing mix on hand at the time. Good idea to make it in jars so it is always available. I'll think about patching in the future.

just did this last night, i took a coir brick, hydrated it in the sink, jared up as much as possible and stuck the rest in a large spawn bag, PC'd jars and pastuerized bag of coir in oven w/ another large bag of straw/dung

now i just have to PC some jars of verm to go w/ it... might just through that in a bag in the oven again too

Hey scat, What if I'm using hydrated lime? Would 1 tsp of hydrated lime be good for about two cups of 60/40 mix? I don't have any pH indicators...

I wouldnt use hydrated lime on coco coir. You want a long term buffer, that isnt water soluable..such as limestone or powdered oyster shells. Hydrated lime will imediatly react to your pH, which should start at a neutral 7. The whole point of the buffer is to get the pH to remain 7 over time. Hydrated will do it instant though and could raise the pH way to much..and wont have any long term effect. With peat based casings, I suggest a long term buffer in addition to the hydrated lime though. I do suggest trying out peat moss too...I have and wont be prepping coir anymore...peats done basically the same way though..

How long will the jars last moisture and all if you don't case them right away?

If the jars are fully sealed and sterilized with no filter patches then they will hold their moisture indefinitely.

Yep :smile: thats what I do...well these days I use bags with a loose rubberband around them..more casing mix per run. Find some autoclave (PP) bags.

Why not seal the jars with the rubber side down?

Would you be able to sterilize or pasteurize the mix in a pan instead of using a PC because I am without one at the moment?
