[Underground Mushroom Gardens]:
Space can be made underneath dwellings. This gives easy access to the space.
Open space can be used too or already underground constructions.

The low temperature, the absence of light, and humidity are good conditions for pro-duction of mushrooms.

Before one starts to produce mushrooms it's good to know the condition of the soil, then map existing underground architectural structures such as tunnels, water and sewer system, pipes for gas and electricity.

[Short about mushrooms]:
Fungus is one of the kingdoms of life. So far around more than 100.000 different species have been found and written about.

It can be difficult to see the fungus since most of it is underground or growing in other materials. The part that is underground is called mycelium and is a fine white network of filaments. It can expand up to 1km. per day. The mycelium can cover huge areas of land and weigh up to several tons. The biggest living organism is a fungus.

A mushroom is the "fruit", which pops up of the soil, from the mycelium. It's just a minimum of the fungus that has these "fruits".

The mushrooms don't have photosynthesis like plants. They are saprophytes. They live as parasites on other living materials (for instance worms and other fungus) or dead material (leaves). To reproduce they spread their spores.

Mushrooms live in different environments all around the world. There are many different types of mushrooms and many different ways they spreads their spores.


[Examples of how fungus is used by persons]:
Fungus is being collected and cultivated inside and outside.

They are used as food, soil improvement, medicine, drugs, biological weapons, and to clean soil and other polluted materials


[Mushroom Composts]:
The mushroom compost consists of a bottom layer of straw and manure that have been pasteurized, mushroom mycelium and a top layer of peat mold without added chemicals. The compost is moisturized with water and at harvest the amount of water needed is the same as the weight of t he mushrooms harvested.


[Light, temperature and humidity]:
This depends of what kind of mushroom there will be farmed.


[Soil]:
The conditions of the soil have to be categorized. Both in relation to the conditions for the farming and for the underground architecture construction.


[Construction]:
A construction has to be developed in relation to the conditions of the underground. Unused space can be used as well, like air-conditioned places underground.
