We had our first public appearance with our open-source Mushroom Growing Fridge aka ’Growfridge’ at the Open Source Circular Economy Days Helsinki 2016.
What is a Growfridge?
A growfridge is a micro-mushroom farm. The main component is a refrigerator. This is retro-fitted to create optimal growing conditions for mushrooms to grow and fruit. With this ”Growfridge” you can have a growing and fruiting room to cultivate up to 3 kg of fresh oyster mushrooms per month at home.
The workshop consisted of drilling holes in the fridge for air-exchange and installing a CPU-fan, a humidifier, a lamp and hygro/thermometers.
- a refrigerator with 2 compartments
- an ultrasonic humidifier (we used a Trixie Fogger XL)
- a water-proof lamp
- a hygro/thermometer
- a CPU-fan (12V, about 0,1A)
- an adapter 230AC – 12DC
- 3 timers
Before the workshop we connected the CPU-fans to the adapter to make them run on 230 AC.
