Mitä on Helsieni?

Helsieni on kiertotalousyritys, joka kasvattaa sieniä läheltä saaduissa raaka-aineissa kuten kahvinporoissa. Tavoitteemme on tuottaa paikallista ja terveellistä ruokaa Suomessa ja sen lähiympäristössä. Helsieni on vastikään aloittanut yritystoimintansa ja etsii ihmisiä ja yrityksiä, jotka uskovat ruoan paikalliseen tuotantoon, kaupunkiviljelyyn ja kiertotalouteen.

The Helsieni Farm

The Helsieni Urban Mushroom farm currently consists of two ex-Reefer shipping containers situated on the parking lot of Hernesaarenranta 3, across the street from Löyly, one of our two coffee waste suppliers. 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

Oyster mushrooms are rich in minerals, vitamins, proteins and amino-acids, contain zero fat and most importantly, they are delicious! If you would like to purchase our mushrooms, please get in touch!

Spent substrate

Our substrate is food for many organisms in nature like plants, worms and even insects. We produce about 150 kg a week of this stuff and we give it away for free! The benefits of using spent mushroom substrate are:

  • During the first season it might still give mushrooms!
  • Great for mulching your plants.
  • High quality 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 a big bag (1m3) delivered, please get in touch!
