(daily feeding and observing)
A Sealable glass
Mushroom substrate from the pink oyster mushroom (for example available on the internet, see below in the links)
Fresh but cold coffee grounds
A clean paper towel
Step 1: Everything must be clean!
Everything must be clean for avoiding contamination by bacteria. At first, you must wash your hands thoroughly. The glass you are going to use must be sterilized by boiling it off with hot water for a few minutes. Please don't use any detergents, your fungus doesn't like them at all.
Step 2: Mushroom substrate
Fill the glass with mushroom substrate up to one finger-broadly. If you don't like using your hands you can use a boiled off spoon instead.
Step 3: Coffee grounds
Next you are adding the coffee grounds in a ratio of 1:1. The coffee grounds should be neither too dry nor too wet.
Three-drop-rule: While pressing the coffee ground in your hands there should be maximal three drops falling out of it. When the coffee grounds are too wet you can squeeze the excessive water out of it.
Step 5: Wait
It is time to show some patience. Place your glass at a dark spot, for example inside a cupboard. Furthermore, it shouldn't be too hot. It will take some days until your mycelium is growing and cutting its way through the coffee grounds.
Keep an eye on your glass. In the case of contamination, it is possible that mould grows. You will recognize mould by the colour of your mycelium, if it is not white, it is mould. Another sign for mould is a bad smell. When you noticed mould, sadly there is no other option then disposing the glass. But don´t give up, try it again!
Step 6: Hooray, Feeding time!
Your mycelium is white and looks super fluffy and went all the way through the coffee grounds? Now it is feeding time! You should feed it daily with fresh coffee grounds. Take care with the cleanliness. That means just use thoroughly washed hands or boiled off spoons.
Step 7: Get creative!
Your mycelium is great and strong then you are already a successful mushroom grower. But of course, this is not the end yet! It is time for getting creative! Here some ideas, what you can do with your mycelium:
You can split your mycelium to try a few ideas.
Perhaps a mushroom will soon grow from your strong mycelium! That is the part you can eat when it is cooked since the pink oyster mushroom is an edible mushroom. By the way, the spores are harmless.
You should look for a nice cooking recipe and give yourself a treat for your good job!
