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
YOUR QUESTIONS, ANSWERED.
Everything you need to know before choosing your kit and getting started.
01 How does the Spray & Grow Kit work?
Open the kit, make the opening, mist as directed and place it somewhere suitable for fruiting. The kit does the growing work while you provide the right conditions and a little regular care.
02 Is it suitable for beginners?
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.
03 How long does it take to grow mushrooms?
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 to develop over the following days.
04 Where should I keep my kit?
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.
05 How often should I mist it?
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.
