What growers say
“It was my first time trying a Lion's Mane mushroom and it was delicious. I'll be reordering soon.”
“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.”
“The online instructions were extremely simple and in literally just over a few weeks I harvested my first Lions mane mushroom!”
NEED TO KNOW
Everything you need to know before choosing your kit and getting started.
Inject the MushBag with your liquid culture, then leave it to colonise in optimal conditions. Once fully colonised, follow the fruiting instructions and grow your mushrooms directly from the same bag.
Yes. The MushBag is designed to make mushroom growing simple, with grain and substrate already combined in one pre-sterilised bag. Just follow the instructions through inoculation, colonisation and fruiting.
Growing time varies depending on the mushroom variety, culture and conditions. The bag first needs to fully colonise before fruiting can begin, so follow the progress of the mycelium rather than relying on a fixed number of days.
Keep it in a clean place indoors, away from direct sunlight and strong heat sources. The ideal conditions change between colonisation and fruiting, so follow the instructions provided with your kit.
You do not need to mist the MushBag while it is colonising. Once you move to the fruiting stage, follow the care instructions and maintain suitable humidity without leaving the block waterlogged.
Yes. The MushBag arrives pre-sterilised and ready to inoculate, but a liquid culture syringe is not included.
The MushBag can be inoculated with your chosen suitable mushroom liquid culture. Growing times, yields and fruiting requirements will vary between varieties.
Many mushroom varieties can produce more than one flush when cared for correctly. Results vary depending on the species and growing conditions, so follow the instructions for your chosen variety.
