Description

King Oyster spore print is collected by placing a mushroom cap (grown indoors) on a piece of paper or aluminum foil and allowing the discharged spores to collect and form a print. Prints can be used to grow mycelium on a sterile petri dish.  While we take every precaution to maintain sterility we cannot guarantee prints are completely free of contaminating organisms.

Cultivation Difficulty: Easy
Type: Edible
Substrate: Pasteurized straw, wood chips, sawdust, various grains, coffee grounds, agricultural waste, newspaper and cardboard. With additional casing layer on top of substrate.
Colonization/Fruiting Temperatures: 70-75F/60-70F

This is the common temperate oyster mushroom. King oysters are aggressive and very hearty mushrooms producing high yields.

As with all oyster mushrooms, king oysters need plenty of fresh air to develop normally. High carbon dioxide levels from mushroom metabolism will accumulate in sealed growing environments and can reduce cap size and elongate stems severely.Fruiting in open humidity chambers with frequent fresh air exchange will produce best possible yields.
