Coir and Coconut Allergies
    #18725516 - 08/19/13 12:01 AM (10 years, 5 months ago)

Hello Shroomery! I'm still new to this, but I just had my first harvest today, from the shake of a bag of dried mushrooms, believe it or not, and I have to say this hobby is fascinating and fun! So, like (I'm assuming) most new growers want to expand their styles. My PF Tek went well, and now I want to start some WBS trays.

Now, from what I've read, coco coir is superior to verm for casings. My friend (the one that bet me I couldn't grow from shake) is deathly allergic to coconut. Would coir trigger that, or would it just be from the nut meat?

Not sure about the allergies part, that would depend on what exactly in The coconut your friend is allergic to. I can say though that coir is not superior to verm as a casing. Coir is actually not a casing material at all, Casing materials are non-nutritive.

So coir as a casing won't work?

Not as a casing..it's nutritious..so the mycelium will simply colonize it like the rest of the substrate...a casing is non-nutritious, and keeps a perfect micro-climate for your shrooms to fruit...

Coir only seems to act as a casing because it is naturally contaminant resistant.  If you are using coir as a "casing" you are actually spawning to bulk.  Yes, it can work.  No, it's not the best idea.

How did you reanimate the shake? Just dropped a bit on agar and added a drop of distilled water and hope for the best? Did you get contams you have to transfer away from? I've heard of this being done. Nice job.

There should be enough moisture in the agar that you wouldn't need to add any water.. :smile:

I can't say whether coir would contain the proteins that elicit your friend's allergic reaction. Coir is that fibrous stuff on the outside of a whole coconut that you buy at the supermarket. It's easy to imagine that the allergens are all in the flesh of the coconut, but I'm afraid I don't know. Even if someone authoritative claims it's safe, if your friend really is deathly allergic, I wouldn't risk it.

But before we go further, let's make sure we're talking about the same thing, because the terminology is often muddled and misused.

A bulk substrate is a nutritious material that mushrooms can grow on, but it's not quite nutritious enough to support vigorous growth on its own. It is generally pasteurized and then mixed with fully colonized grain spawn. Coir is a popular bulk substrate. So are straw and manure.

A casing is a thin, moist top layer, very low in nutrition. It is applied on top of bulk substrate or just on top of colonized grains. Its purpose is to help maintain a high-humidity environment at the surface. People used to use coir as a casing material but it is no longer recommended, partly because it actually is nutritious. Vermiculite can be used as a casing but it's not great on its own. Peat moss is often used, either mixed with vermiculite or on its own. Some people use potting soil. Some people use polymer water crystals.

So, the way I see it, you have two options:

1. Use a bulk substrate other than coir. Use some combination of straw, manure, and vermiculite. More care needs to be taken pasteurizing straw and manure than with coir, because they're not as contamination-resistant.

2. Just case the fully colonized wild bird seed with some combination of peat moss, potting soil, and vermiculite, and fruit it without a bulk substrate. This is easy to do, but results in smaller yields. You could improve on this somewhat by using grains that can hold more moisture than birdseed, like rye berries or wheat berries.

You could, of course, use a bulk substrate and also case it, but cubensis spawned to a bulk substrate generally does fine without a casing layer.

If you do end up using the coir, just be sure to wear some gloves, long sleeves, a dust mask, and have no fans running in the work area as to not throw any coir pieces into the air. There are a few different bulk substrates you could use just be on the safe side. Good luck to ya!

Believe it or not, I did it as it it were a spore print, and rehydrated it in the syringe. Out of 5 pint jars, one contamed early, and another did right before birthing.

The coir may not contain his allergens but it's unknown without testing.  Doctors often do scratch tests with trace amounts of the allergen to see.
The mushies themselves should not contain any of the allergen, so unless he is hyper allergic to even the dust giving him snipped substrate free ones is also an option.

Coir is a medium nutrient material used to bulk up a substrate.  While it's often the most recommended many other things can be used.  Hpoo is a common alternative.
