All rainwater is collected and stored in our basins, some of which are located under our production floors. We use this water to irrigate the crops, after which the water is collected and reused. This is a so called closed system. The collected water is purified again and again, so that the plants get fresh and clean water and no used water goes back into nature.
The challenge for sustainable cultivation is to make the plant as strong as possible and thereby make it resistant to diseases and pests If the plant is resistant and less susceptible, small animals can take over to keep the crop healthy. This way we can keep cultivation under control with as little use as possible of chemical crop protection products. In other words, diseases and pests are combated as much as possible biologically. Employees continuously walk through the nursery to ensure that the plants are strong and healthy.
The electricity we need for Geest Potplanten is generated with enormous batteries, so-called CHPs. In the summer, we collect the heat and store it underground, which we can use it in the winter to heat the greenhouse and vice versa. There are sources present under the company, which we also use for energy efficiency. In summer, cold water from the springs is used to regulate the temperature in the cool compartments. One of the cultivation phases for orchids has been set up as a cold department to get the plants in bloom. In addition, we have our solar panels to save on electricity and we are connected to geothermal energy in order to use as little gas as possible.
Waste is neatly separated and recycled within the company. Recycled materials are being used as much as possible. For example, the cultivation pots are made of recycled bottle caps and nappies and the trays for the plants are selected on the basis of the reusability of the material. The potting soil used is sustainably sourced and is RHP-certified.
