Mushrooms grow in all sorts of places associated with waste: fungi can grow on paper, on cardboard, sawdust everywhere. Their coincident growth is rather a different thing, but the fact is that growing mushrooms is difficult. You can’t grow them in ordinary garden soil. Organic materials on which mushrooms grow are called mushroom substrates and used coffee grounds work well for this purpose because they are cohesive and already been sterilized during the brewing process.
Used coffee grounds, mushroom spawn with sawdust (oyster or shiitake), a bucket/container of 2 to 5 gallon in size, spray bottle and cellophane.
1. Fill the bucket or container with coffee grounds. Keep in mind, how much it is filled and draw a line over the top of the layer of coffee grounds. Empty the bucket and put coffee grounds back in their original packaging. *Don’t fill it full.
2.
Drill a few holes around a bucket, half-way between the line you just drew and the bucket rim. These holes will be employed later for releasing of CO2, because you’ll cover the top of bucket with perforated plastic film.
3. Fill the bucket with coffee grounds again, if they are dry, moist them. Break the mushroom spawn with sawdust into the bucket and mix this in coffee grounds on top one inch layer so that the spores will distribute well.
4.
Now cover your bucket with a layer of cellophane. Poke some holes in cellophane with a pen for air. This will keep your mushrooms in appropriately moist environment and let the air in and out.
5. Keep this bucket in a dark corner of your home.
6. Remove the cellophane cover once a day to lightly spray the coffee grounds from water. Place the cover back when finished.
After 15 to 20 days, surface of mushroom substrate will start to change
