Two water sources are used:
1 Rainwater collected from glass roof of our greenhouses is stored in a 5 million litre reservoir or in silos. We have a total storage capacity of 8 million litres of clean rainwater. In case of extreme rainfall this helps water boards because it does not end up in the ditches.
2 Ditchwater. This water will have to be as clean as possible.
The water is sprayed over the plants via a water spray system. Whatever the plant does not absorb immediately is collected by waterproof floors, purified and then reused. We supplement any shortfalls with water from the basin.
Pest control occurs as much as possible organically, i.e. through the use of natural enemies, so that we need to use as little plant protection product as possible. For example, we have open windows in the greenhouse allowing bees, wasps and bumblebees to fly into the greenhouse to collect pollen from our flowers. And it is precisely these animals that help to reduce the effects of plant lice.
In addition we are working nice and need with healthy starting materials. Cuttings for the Conifers and Skimmia’s are grown under own management and the tubers for the Zantedeschia/Calla are purchased from our regular growers in Noord-Holland
Concerning energy consumption and emission of gases regarding air pollution.
All waste is separated and the company collecting it processes it into compost, which ultimately results in a reduction of gas emissions.
By working with energy-saving screens, heat stays inside and the use of fossil fuels (natural gas, petroleum etc.) is reduced. In the winter, cultivation takes place in the cold and when it gets warmer, the sun provides the heat in the greenhouse.
All plants are eventually transported to the customers with a Euro 6 truck. This generation of lorries makes a major contribution to cleaner air.
