150g of animal litter (natural, organic, compressed wood)
300g of water
One spoon of starch (potato or manioca)
4% of ecologic honey (cane sugar or molasses is also fine)
Dilute the honey and starch into the water, then add it to the wooden bits. Soak the wood litter in water for a while. When the wood is fully absorbed, it doesn’t have to show extra water on the ground, nor dried parts either. Leave it rest for sometime.
Steam sterilize the jar
Put the wooden bits with all the ingredients in a jar (the lid of the jar must have an air filter, see previous articles on how to do it).
In a pot, put some water on the ground, then keep the jar lifted up with some metal structure. turn on the fire and when the water boils, keep the jar to steam-sterilize for about one hour.
The procedure is the same as explained in previous articles: with all the environment clean and the tools sterilized, cut open a piece of Pleurotus Ostreatus mushroom and put some pieces of the internal side of it in to the jar.
Close the lid and keep the jars at about 23 degrees Celsius for a bunch of weeks.
Your jar will be fully colonized when you see the white mycelium running all over it.
Now you have a full jar of spawn ready for the inoculation of your final chosen substrate to grow the mushrooms on.
Pleurotus Ostreatus (but other types of Pleurotus family as well) will grow on almost any ligno-cellulosic material.
A short list of products could be: straw, corn cobs, sawdust, cork, banana leaves, cotton seed hulls, newspaper, cardboard, toilet paper rolls, coffee pulp, sawdust, cocoa, peanut and coconut shells, cotton seed hulls, Jamaica, cassava peels, cotton, sorghum, corn stalks, grass, clover, wood, wastes of rice, wheat, cotton from textile industry, corncobs, crushed bagasse and molasses from sugar industry, water hyacinth, water lily, bean, wheat straw, leaves, oil-palm fiber, paper and paddy.
Today I will write about making your own liquid culture for mushroom growing.
The liquid culture is a liquid mix of nutrients that will help the mycelium to grow healthy prior to inoculation. It’s very effective cause with a very little amount of liquid culture you can inoculate directly a big amount of soil or spawn.
These are the expanded notes of a workshop I was participating a while ago. You can maybe find some useful information in here, it’s a sort of a very resumed article that explain a method for cultivating mushrooms on your own at home + some background information. More than a guide, is an overview over the method. Enjoy!
Mushrooms that grows in the nature are mainly decomposing the matter. They are at the base of life: they break materials like lignine, cellulose and minerals and splitcomplex elements into smaller chemical substances that are beneficial not only for the organism itself, but also more easily absorbed from the organisms in the surrounding environment.What we call “mushroom”, is just the visible part of a very extended system of “roots” (hyphae) called mycelium, which is the actual organism.
Today I will write about growing Pleorotus Ostreatus – the Oyster Mushroom – in a plastic bottle.
As substrate, I used spent coffee ground (about 60%), carton (20%), peanut and pistachio shells (20%).
I used an empty water plastic bottle, made in PET 1 (Polyethylene).
Details: The bottle is 1.5 Liter and I used water between 60 and 80 degrees to sterilize it internally, just a couple of washes. In addition, you can add some alcohol inside (don’t inhale in case you do this, hot water + alcohol creates gasses!). Higher temperatures are also possible, but water at 90-100 degrees modify the structure of Polyethylene 1, so it should be used very shortly.
