Cultivators steer crop growth on the basis of climate and irrigation strategy, which is largely determined by the choice of blocks and slabs. Grodan offers an ideal range of stone wool blocks and slabs that produce uniform quality plants with excellent yields.
Grodan launches Grodan Max with V1.0 Technology – the next breakthrough in stonewool growing media for cultivating specialty crops. In order to develop the optimal stone wool substrate and irrigation strategies for indoor and greenhouse specialty crops, Grodan partnered with the Wageningen University and Research Facility and top growers from all over the world. After an intensive 2-year research and trial program, this resulted in the most innovative Grodan product series so far, for the most innovative growers: Grodan Max with V1.0 Technology.
