Grow mushrooms like a pro
A good climate in the growing room is vital to produce mushrooms at a profitable yield and decent fruitbody formation. rotterzwam has a growing room design that fits that purpose. We offer a complete growing room or just a climate wall to insert into an existing space.

What you need to know about the growing room design
Back in 2014, we published an open-source design for the climatisation of a mushroom fruiting room. The design helped many beginning mushroom farmers to design their own growing room. In 2019 we used that same growing room design to construct our new farm.
But we needed an even better version. We wanted the essence of mushroom cultivation technique, in one mobile and flexible installation. Mobile to meet the demand of a mushroom farmer that wants to be able to grow his production in incremental steps. Flexible so it can be moved [if needed] to a bigger space.
Our growing room for mushroom cultivation hosts the following climate functions:
-> Provides sufficient fresh air
-> Provides a stable temperature for incubation and fruiting
-> Provides a stable relative humidity

Sufficient airflow
Fresh air is the most important factor in maintaining proper mushroom formation.

Temperature control
Proper temperature control provides for the shortest possible incubation phase.

Low tech humidifier
Proper humidity control prevents dry mushrooms during fruiting phase.

We understand that money is a limited resource when starting any company. We always had to bootstrap our operations as much as possible. That's why we offer two options.
Complete room
Our Mobile Mushroom Units [MMU] are fully climatized and optimized for mushroom cultivation of exotic species. Our MMU is built in a standard 40 FT High Cube Reefer. The Mobile Mushroom Unit is very well insulated and can be placed outside. The roof has 80 mm, the walls has 60 mm and the doors have 74 mm insulation. The MMU comes plug and play. That means when you connect the electricity and the water, the MMU is fully operational. You can then start to fill the substrate in the unit.
Climate wall
Our climate wall is optimized for mushroom cultivation of exotic species. It has a ventilation system that can add fresh air or circulate the air in your unit. Our Climate wall is built to fit in a standard 40 FT High Cube Reefer and most sheds, barn or room. Besides a ventilation system the climate wall is supplied with a low tech humidifier and temperature is adjusted with a heat pump that is be connected to a heat exchanger.
