There is also needed to think about some new unconventional and alternative sort of food-stuff. An edible mushroom growing is one of the relatively new agricultural branches, whereby on a large scale there are grown species which belong to saprophytic group. The aim of task was the building – technological and equipment – technological proposal of oyster (Pleurotus ostreatus, Jacq. P. Kumm) production unit with taking account to its specific agro technical requirements and valid legislative. In the next part of task there were evaluated and compared qualitative and quantitative parameters of sporocarps from two variants which were collected in the first growth wave and accuracy of the proposed oyster production unit. In case of variant A there were used sacks with substrates, which have been exposed to cold shock by 6°C temperature for 4 days and in variant B were used substrates without cold shock. According to reached results the cold shock had almost neither influence on production quantity. There was found out an important fact that crop height from first growth wave wasn´t identical with well-known literature sources. The low crop is connected with high CO2 content in oyster production unit room, according to our opinion. Other equipment aimed to air humidity regulation, air temperature regulation and room lights was designed correctly.
