Climate in mushroom growing: what to measure and how to get alerts
Mushrooms respond to three things in the air: CO2, humidity and temperature. A climate controller keeps them in range while everything works. Monitoring is the second layer: it shows each room's history and warns you when something fails, before the crop suffers.
What to measure
- CO2: high during spawn run, lower for fruiting. Too much CO2 in fruiting gives long stems and small caps.
- Relative humidity: high and steady. A humidifier that stops dries the surface in hours.
- Air temperature: the range of each phase and species.
- Substrate temperature: the compost or bags generate heat; a probe inside shows it before the air does.
Climate controller or monitoring?
Climate controllers from brands such as Fancom, Priva, TrolMaster or Agrowtek run the fans, heaters and humidifiers. They are the right tool for control. Monitoring does not replace them: it adds independent sensors in each room, alarms that reach the phone, and the history of every cycle in one place, also across several farms.
| Climate controller | Monitoring platform | |
|---|---|---|
| Job | Runs fans, heating and humidifiers | Measures, records and alerts |
| If the controller fails | Its own alarm, if it has one | Independent sensors still alert |
| Several farms | One controller per room or farm | Every room on one platform |
Where to place the sensors
Put the CO2 and humidity sensor at crop height, away from the humidifier nozzle and the air inlet, so it reads what the mushrooms breathe. In large rooms, one at each end. The temperature probe goes into the compost or a bag in the middle of the shelf.
Alerts and data
Each alert can go by email, SMS, WhatsApp, voice call or push notification in the iOS and Android app, with thresholds per room and phase. The platform runs on AWS (Frankfurt for Europe, United States for the rest of the world) or on your own servers.
