The sharp rise in energy prices is forcing many growers to reduce their lighting, to turn down the thermostat a little and provide screening for longer. If irrigation and nutrient levels are not adjusted accordingly, this can have major consequences for the crop and the roots, warns cultivation advisor Jos Beerens from Grodan. “More economical heating might be desirable, but this has a direct impact on crop activity. When doing so, pay extra attention to irrigation, nutrient levels and cold feet”.
Cultivation advisor and specialist in fruit-vegetable crops Jos Beerens has noticed that many substrate growers are using less energy for their cultivation, sometimes in combination with less lighting. It is not uncommon to forget to adjust the irrigation as well. This can lead to an imbalance in the crop and affect both root and fruit development.
