The Helsieni Urban Mushroom Farm

Every year around the world millions of tonnes of  coffee waste are sent to the incinerator or landfill. Coffee grounds, however, are an excellent source of nutrients and perfect for growing mushrooms. The coffee making process sterilizes the grounds and if used fresh they don’t require additional treatment. Helsieni grows oyster mushrooms on Helsinki’s coffee waste and aims to be part of the city’s sustainable food ecosystem. The Helsieni Urban Mushroom farm currently consists of two ex-Reefer shipping containers. Our current location is Martinkyläntie 43, Vantaa.

We have built and designed the farm for sporeless oyster mushroom  (Pleurotus Ostreatus) production. The total output capacity is around 200kg of mushrooms per month. Oyster mushrooms require very little water and energy to grow and because they are rich in proteins and amino-acids they are very healthy.

If you are interested in buying our oyster mushrooms, please send a message to stephane@helsieni.fi or call +358 466165597.

Spent substrate

Spent mushroom substrate is the waste product of every mushroom farm and severely undervalued. We produce about 150 kg a week of this stuff, and we need to dispose of it because keeping it near our farm increases the risk of contamination. However, you can still use it for many purposes, the most important one: growing mushrooms in your garden! We think spent mushroom substrate is the best mulch ever.

The benefits of using spent mushroom substrate are:

  • You can get fresh mushrooms within 2-3 weeks!
  • Great for mulching your plants.
  • Naturally degrades within 1 year and serves as a slow release fertilizer, rich in N and P.
  • Helps build a healthy population of micro-organisms and worms in your soil.

You can come by anytime and pick up as much as you want. If you would like to have some delivered, please get in touch!
