Erik Boers has an amaryllis cut flower nursery of 3 hectares. For the last few years, he has been working on a substrate of clay pebbles of Jongkind. "We chose clay granules because we have previously had problems with nematodes," says Boers. "After a year's trial, I was convinced: the water-air maintenance is excellent. The step to convert it all was a necessity, not a choice."
In the business, 100% is circulated. "That suits us well. Because the substrate is airy, the temperature is also spread evenly, which does the crop good."
Relatively expensive
"The substrate is relatively expensive, but the structure remains good until the end. Now, everything is going well and all that remains is a little fine tuning in relation to water dosage and fertiliser."
