Heating System
The heating system of a greenhouse usually consists of two main components: the heat generator and distributor of heat. The two elements commonly used to distribute heat are water and air. As for generating heat, several options are available, generally determined by the nature of the fuel to be used: natural gas, propane, biomass, fuel oil, biodiesel, etc.
Climate Control
Climate control is an essential part of greenhouse management. A greenhouse is a means to create a perfect microclimate adapted to the needs of specific crops, regardless of the weather outside. Centralized management of equipment facilitates precise control of heating, lighting, irrigation and other components of greenhouse management.

Cooling
Depending on the climate, it may sometimes be necessary to cool a greenhouse to provide suitable growing conditions for plants that thrive in cooler climates. Whether it's because the temperature rises too much in the summer or because a cool climate crop is grown in a tropical area, several solutions are available to reduce the temperature inside a greenhouse.
Ventilation
Ventilation is essential for healthy crops. When properly done, ventilation will help control temperature, humidity and contribute to the even distribution of CO2 (when needed). There are many solutions available to ensure your crops benefit from optimal ventilation
