Each bell pepper plant in the greenhouse is individually drip irrigated with water and added nutrients. This is a fully automatic process: the computer calculates how much water and how many nutrients the plants need. No valuable resources are wasted, and the perfect conditions for growth are created.
Any water that is not absorbed by the plant is collected, purified and reused.
The bell peppers grow under the best conditions possible. Insects that are harmful to the crop are controlled using biological methods that deploy natural predators in the greenhouse.
Dutch growers are at the forefront of finding alternative sources of heat for their greenhouses. This approach ensures we can minimise our use of fossil fuels, for example by using geothermal energy.
Another contribution to energy-efficient growing is the so-called CHP installation: a combined heat and power unit that supplies electricity, heat and CO2 after combustion of gas. The electricity is supplied to the external grid, and surplus heat is stored in a heat buffer.
