Choosing a King Oyster Grow Kit

We stock King Oyster as a all in one grow bag and fruiting block. Ready to fruit options arrive fully colonised, so you simply open, mist and harvest, while our all in one grow bag bundles include a King Oyster liquid culture for you to inoculate yourself. Expect your first harvest in around two to three weeks once fruiting begins.

How to Grow King Oyster at Home

Keep king oyster cool and humid with moderate fresh air; higher carbon dioxide encourages the long, thick stems it is famous for. King Oyster fruits best at around 10 to 18°C.

Cooking and Using King Oyster

Slice the stems into rounds, score them and sear like scallops, or shred them lengthways for a pulled texture.
