Climate control is what turns a greenhouse from a summer-only space into a year-round growing environment. It comes down to managing three things — temperature, airflow and humidity — with the right mix of ventilation, heating, shading and monitoring. This hub links the equipment for each.

The three things to control
- Temperature — vent and shade to stop overheating; heat to hold a minimum in winter.
- Airflow — constant gentle air movement prevents disease and evens out heat.
- Humidity — too high breeds disease, too low stresses plants.
The equipment
- Ventilation & fans — roof/side vents, automatic openers and circulation/extraction fans.
- Heaters — electric, gas or paraffin to hold a minimum temperature.
- Shade cloth — cuts summer heat and scorch so vents can cope.
- Thermometers & hygrometers — you can’t manage what you don’t measure.
