The crop grows and produces optimally when there is a good balance between the production and consumption of assimilates. As a grower, you can control this balance. One way of doing this is by matching the temperature to the available light. This is only possible if you have a good overview of the light sum. That’s why it’s so important to measure PAR light in the greenhouse.

The switch from HPS (High Pressure Sodium) to LED lighting is more than just choosing to use a different fixture type. The energy balance in the greenhouse changes considerably and so additional cultivation measurements are required.

Using screens more intensively can help save energy, but it can also lead to higher humidity levels in the greenhouse. This affects evaporation, water and nutrient uptake, and conditions in the root zone.

Growers are looking for ways to reduce costs due to energy consumption, especially now. This can be done by applying temperature integration over several days. So smoothing out peaks in energy demand and focusing on average greenhouse temperatures, can save energy.
