-====== Aim ======+====== Mushroom production at Kuckucksmuehle ======

 +===== Aim =====
  
 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.

 If this proves successful, supplying fresh mushrooms to nearby shops and restaurants should be considered, increasing the production accordingly. If this proves successful, supplying fresh mushrooms to nearby shops and restaurants should be considered, increasing the production accordingly.
-====== Proposed setup ====== + 
-===== Location =====+After some consideration it was decided to try growing Oyster Mushrooms initially. This is because they are easy to grow, as they grow well in a wide range of environmental conditions. There are several varieties of various oyster mushrooms: 
 + 
 +  * Oyster mushrooms 
 +  * King oyster mushrooms 
 +  * Golden oyster mushrooms 
 +  * Blue oyster mushrooms 
 + 
 +==== Projected output volume and savings estimate ==== 
 + 
 +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.
