The Black Pearl (Pleurotus ostreatus hybrid) mushroom is something truly special.

It is a hybrid between King oysters and Grey oysters.

It produces wonderfully chewy mushrooms like the king oyster but they grow as fast and agressively as the grey oyster.
Perfect for home cultivators!

If you plan to use the Black Pearl grow kit in regular room temperature we recommend that you store the kit a couple of days in the fridge before you start it. This since Black Pearl is a mushroom that thrive in lower temperatures.

The cold initiates the mushroom growth and if you don't give the kit a cold shock it might take a long time for the mushrooms to start developing.

Our grow kits are made at the site of our mushroom laboratory located in the Finnish countryside.
Just follow the instructions and you can enjoy fresh mushrooms grown at home in a couple of weeks time!

When making the grow kits we mix sawdust, wheat bran and water together.
 When the substrate mix have been packaged into grow bags they go through sterilisation.
 After the bags have been cooled down we inoculate them with mycelium that is grown on site.

That is it! No chemicals or nasty stuff!
