Grow your own Mushrooms at home

1 oyster mushroom

There are quite a number of mushroom species that lend themselves well to home indoor cultivation. One species in particular, the Oyster mushroom (Pleurotus Ostreatus), a true wonder of the fungi world, is ideal for the beginner mushroom cultivator. It is one of the most ubiquitous and vivacious species of fungi on the planet. Not only is it a delicious gourmet mushroom but it is also has huge potential to remediate damaged and polluted environments. It is the third most commercially grown mushroom in the world not that you’d be able to tell from our supermarket shelves. Many people seem to be under the impression that mushrooms have little nutritional value. Well this is not true of the oyster mushroom. It contains up to 30% protein and it is high in vitamin C and potassium.

Pleurotus Ostreatus is among the pioneers in the field of mycoremediation. It is a saprophytic mushroom meaning that it feeds on ligneous, woody material. However, the oyster mushroom is especially adaptable to many different types of cellulose rich substrate. So much so that it is being used to denature oil contaminated organic matter reducing petrol-chemical soaked material to organic compost in a matter of months far out performing conventional chemical treatments for oil spills and related pollutants. It does this by producing various enzymes that breakdown a wide assortment of hydrocarbon-based toxic substances. This means it also has the potential to filter such pollutants from water using a fully inoculated substrate as a “mycofilter”.

This virulent versatility means that you can easily grow this mushroom at home on a variety of substrates such as cardboard, straw, paper, to name just a few and here’s how.

You will need:

  • cardboard
  • plastic container
  • straw
  • plastic bag (freezer bag)
  • gypsum(optional)
  • used coffee granules (optional)
  • scissors

First, soak some cardboard (preferably without print) in boiling water leave to cool, and then drain off the excess water.

Take a healthy fresh specimen preferable with the root or stem butt and slice thinly.

Once the cardboard has cooled and drained (the cardboard should be wet but not dripping) peel the layer and using the corrugated sections lay them in strips in the plastic container. You are trying to create an undulating terrain for the mycellium to grow/run through. Sandwich pieces of the sliced mushroom between layers of the cardboard until the container is full.

Now put the lid on the container but leave it very slightly open, place the container in a dark warm place for one to two weeks until the the mycellium has fully colonised the container.

Once you have a container thick with white mycellium with a sweet nutty aroma you are ready to use it to inoculate your chosen substrate for the mushroom to grow on.

Substrate:

Cut the straw into 1 to 2 inch pieces put into a large saucepan, cover with water, bring to the boil and simmer for 30 mins. This process of pasteruization should remove most bacteria and fungi that would otherwise compete with the oyster mushroom. Now leave to cool and drain. The moisture content should be 80% basically not dripping wet. Take a clear plastic bag and layer the straw and the cardboard mycellium until full. Tie the bag tight. It’s good to have some air exchange. Ideally at micro porus filter would be used to prevent contamination but with oyster mushroom this isn’t so much of a concern. Now leave the bag in a dark warm place for three weeks until it is a firm whitish block of mycellium. Now it’s ready to fruit!
