Made, the Netherlands, 9 January 2012: In greenhouse trials carried out over the course of 2011 at the facilities of PlantResearch in Made, the Netherlands, the DP Optima™ double layer coco slabs from Dutch Plantin were found to require 10 to 20% less water and fertilizer feed than rock wool slabs of similar dimensions, while still producing the same tomato yield. This would not only make coco slabs well suited for areas where water is a limiting factor in horticultural production, it also provides sustainability benefits in horticultural advanced regions such as Europe or North America.
