Organic White Oyster Mushroom Grain Spawn

The white oyster mushroom (also called Elm oyster mushroom) is one of the easiest varieties to grow. Its mycelium adapts to a variety of different substrates and is resistant to contamination.

It can be grown indoors or outdoors on mulch in the vegetable garden for example.

This variety of oyster mushroom produces large white caps, which can sometimes reach 15 or even 20 cm, particularly on second harvests.

Mycelium storage: 1 month in the fridge

Note: This variety is part of the Pleurotus ostreatus and bears the name "elm oyster mushroom" in association with the hypsizygus ulmarius with which it is generally confused. This variety is more productive and easier to grow indoors than hypsizygus ulmarius.

Growing conditions

It can be grown indoors all year round. Even more than other varieties of oyster mushrooms, this one is very sensitive to CO2 levels.

In indoor cultivation, it therefore requires good ventilation to limit the size of the plants and promote the width of the caps.

In outdoor cultivation, sowing is done at the beginning of spring to harvest at the beginning of summer or in autumn. It is necessary to keep moist in case of drought.

Substrates

Straws pasteurized with lime or heat, pasteurized sawdust and other lino-cellulose materials.

Indoor or outdoor cultivation.

We recommend our ready-to-use substrate , particularly suitable for wood-eating varieties.
