Produce enough mushrooms to meet local demand for mushrooms, eliminating the need to buy mushrooms. This should be as low-maintenance as possible and as automated as practical. | Produce enough mushrooms to meet local demand for mushrooms, eliminating the need to buy mushrooms.

+ | The proposed setup uses 24x5l buckets, spread out in 6 batches of 4 buckets. | ||
+ | |||
+ | Each 5ltr bucket is projected to produce an average of 0.2kg of edible mushrooms every 3 weeks, which is about 1.6kg of mushrooms / week. Mushrooms cost €9/kg, so each week will save €14.40 in mushrooms. Over 1 year it is expected to save €750, producing 83kg of edible mushrooms. | ||

Spore exposure can initially lead to flu-like symptoms, and then develop into a permanent mushroom allergy. To avoid that, spore contamination of people should be avoided as much as possible. At the same time, when working with mushrooms, the intended growth sites should not be contaminated by things that we do not want to grow.

- | TODO: Instructions | + | The straw leftover form the mushroom production can be added to the garden compost when in large quantities or the vegetable compost in smaller quantities eg. 1 bucket a week is ok for the vegetable compost but anything over this would have to go in the garden waste compost as it would need to be mixed with additional organic matter to compost effectively. |
