Our Elm Oyster Grain Spawn Bag arrives already colonised, ready to be added to your substrate without messing about with spores or culture. This means faster results and more of the fun bits.
Elm Oysters are tall, pale and graceful looking tasty favourites. With a slight earthy tasty, they complement many dishes extremely well including pasta, risottos and all kinds of sauces. They fruit fast, so under good conditions (warmth, humidity, airflow), you’ll see flushes in about three weeks.
Use in monotubs, bags or block substrates — wherever you have space and decent airflow. Mist gently, maintain high humidity, give fresh air once primordia begin forming, then let the mushrooms stretch out. The texture is meaty, the colour stunning, and the harvests generous.
If you want something easy, tasty and fun to grow, this is it. Elm Oyster isn’t just about aesthetics. It brings tasty meals, a bright splash of colour, and a lot of joy. Great for beginners and experienced growers alike.
