Dehumidification trial at van Koppen nursery Dehumidifier boosts yields, cuts disease pressure and saves energy

Dehumidifier boosts yields, cuts disease pressure and saves energy

A giant dehumidifier in cherry tomato grower Robert van Koppen’s greenhouse in Kwintsheul (Westland, the Netherlands) keeps the RH below the critical value of
A different growing strategy is a potential key to saving energy. An important part of this is to slow down transpiration.

Slowing down crop transpiration cuts energy consumption

The focus of energy savings usually lies in technology. But the crop itself offers numerous opportunities to economise on energy consumption. Many research results
Researchers have been working with screen manufacturers to develop an objective method of determining the energy saving performance of screen fabrics.

Energy-saving screens can now be compared objectively

Screen suppliers each have their own methods of determining the energy-saving performance of their screens, making it very hard for the grower to compare
Limiting light emissions called for creative solution

Combining two vertical fans makes for more even climate

Assimilation lights give off a lot of heat which stays at the top of the greenhouse when you would rather have it down near

Energy efficient production according to the principles of Next Generation Growing, without any additional investment, is the aim of pepper trial being carried out
Commercial phalaenopsis growers use a lot of artificial lighting. Research indicates that timing of the lighting is more important than the total light sum

Can you save electricity by dimming both morning and afternoon?

Phalaenopsis growers sometimes use artificial lighting for 16 hours per day, totalling 8 to 10 mol/m2/day, especially in the winter. For a crop with
He is the first tomato grower without artificial lighting in the Netherlands to have two transparent energy screens and no dehumidification.
