What growers say

“Despite being rather neglected during a house move our blue oyster kit has produced an amazing crop of mushrooms (with more on the way!).”
“Martian Mushrooms’ Golden Oyster kept on producing strong, colourful, and beautifully clustered right through January, in the middle of a UK winter.”

Yes. The kit is designed to make growing gourmet mushrooms approachable, even if you have never grown mushrooms before. Follow the simple care instructions and keep an eye on moisture and airflow.
Growing time depends on the variety and the conditions in your home. Once the kit is opened and cared for correctly, you can expect visible growth in as early as 10 days.
Choose a clean spot indoors with indirect light, fresh air and a comfortable room temperature. Avoid direct sun, radiators and places where the kit can be knocked over.
Mist according to the care instructions included with your kit. The surface should stay suitably moist, but it should not be left waterlogged. Your environment may affect how often misting is needed.
