The Helsieni mushroom farm
Our mushroom farm consists of two insulated shipping containers, where we grow delicious mushrooms, and a greenhouse built on them. The oyster mushrooms love to grow in our substrate of straw and used coffee grounds. Just next to the farm there is our office where all the Starter Kits and Growkits are prepared for you to grow your own mushrooms on your morning coffee grounds at home.
Local Food – Fresh mushrooms
Our oyster mushrooms are available around the year! You can get Helsieni’s locally produced fresh mushrooms on your table in the Helsinki Metropolitan area. The mushrooms are at their best when they are freshly harvested, but they store in the fridge for at least 10 days. We also cooperate with seasonal mushroom pickers and growers so that we can offer you a broader selection of mushrooms during the late summer and autumn.
Seedlings & herbs
Stunning dark purple tomatoes, charmingly pink striped eggplants, compact yellow-variegated cucumbers …
Our greenhouse, improved with the heat and carbon dioxide produced by our mushroom containers, is full of seedlings of exciting and delicious vegetables! Find your own favorites for your balcony, greenhouse and open vegetable garden.
Mushroom farming innovation
The Helsieni farm in Espoo is a pioneer of urban modular mushroom farming in Finland. For us modularity means flexible production than can be scaled up or down, unlike big factories, as demand fluctuates. We are developing and using low-tech solutions for growing food in the cities. We try to incorporate circular economy principles in all elements of our business. Our farm is continuously developed based on the research we make in these areas.
We believe in open source and sharing knowledge. Below you will find our publications.
In the natural world there is no concept of “waste”, everything is food for something. In our organization we intend to maximise the use of organic materials for mushroom production. We use for example coffee ground waste from restaurants, offices and cafés as a part of the substrate for the mycelium. After producing mushrooms at the farm our spent substrate is used in outdoor mushroom growing – like in mushroom beds – or in garden work or composted. So in the end all the organic material returns to the soil.
Our environmental impact can be reduced if we treat non-organic materials as precious and try to reduce, reuse, repair them. We want to grow mushrooms using as little plastic as possible and using commonly available tools and equipment instead of high cost specialized mushroom equipment.
We want our farm to use as little energy as possible. We are developing methods that avoid needing energy and we are designing our systems so that they can switch to renewable energy if needed.
Helsieni offers consulting around building and setting up a low-tech oyster mushroom farm, with minimal capital investments. Although we have most experience in the Finnish context a lot of the knowledge applies no matter where you are. Whether you need technical assistance and are thinking about how to design your humidity or air-flow systems, or want to know more about substrate production and farm layout, we are happy to help. We can do a virtual / phone session or host you at our farm in Espoo. Just send us a message and we’ll be in touch!
Tours & workshops
We organise tours and workshops for private groups, schools or associations. Come and learn about the fascinating life of fungi, mushroom farming or get your hands dirty and grow them at home!
