Larger water buffer
Ronald also decided to reserve a part of his three hectare large nursery for growing on Multigrow slabs to compare results. The flowers have been harvested for a few months. Van der Salm: “First of all I noticed, that the rockwool retains much more moisture than coconut fibre. The slabs remain wetter. I find this an advantage during the summer. We now can afford to have a problem with the water supply.”
Cubes are more sustainable
However, the big difference is, according to van der Salm, that rockwool slabs are more sustainable than coco slabs. Van der Salm: “Coco is usable for two years. I can grow longer on rockwool because it is useable for three to four years. This is an economical advantage. When over two years the coco is no longer usable, there is a very good chance then that I switch to rockwool slabs.”

The nursery comprises of a greenhouse covering an area of 33,200 m2 where both standard gerberas and the mini gerberas are being cultivated in a biologically integrated and sustainable way. We had the privilege of being the first in the Netherlands to have 100% biologically grown shoots be delivered. Out of Delfgauw the total European market is served. Per year 20 million stalks find their way to the consumers through wholesalers. Year-round this adds up to 40,000 flowers of high quality which leaf PURE gerbera.
