Sustainable lettuce cultivation

The cultivation methods of Deliscious provide for lettuce of a consistently high quality. Moreover, we continually strive to achieve the most sustainable production methods possible. This means: producing plants that are less vulnerable to diseases and plagues, as well as finding economical ways of handling energy and water.

Less vulnerable lettuce

Because the lettuce is cultivated in gutters and not in the ground, the plants are less vulnerable to diseases and plagues. Therefore, the use of pest management resources can also be limited. Furthermore, the harvest is inspected by an independent agency (TNO) on a monthly basis. Deliscious considers it important that its root-ball lettuce satisfies the highest environmental requirements.

Saving energy

Deliscious limits its energy consumption as much as possible. Naturally, lettuce plants need warmth to grow. We can provide our lettuce plants with the ideal temperature, because they grow at a height of one meter above the ground. As a result, we can save a considerable amount of energy. Moreover, we employ a system that keeps the greenhouses as full as possible. The distance between the gutters is adjusted according to the growth stage of the plants. Eventually this system requires less energy per head of lettuce. In addition, we store away the excess heat that arises in the climate chamber in the ground, in order to use it again for heating the greenhouses if necessary.

Saving water

Water usage is also limited as much as possible. We nourish our lettuce plants with water through the gutters, which form a closed system together. After the water is used, it is directed to a purification installation. After the water is purified, we use it again. This way we hardly waste any water. All the water used comes from rainwater, collected in large water tanks during downpours.
