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.
Initial saturation of the Grodan Max is essential for successful cultivation. It is the basis for optimal root development and growth of your crop. The products that you receive from us are produced with maximum care and to guarantee successful use of them, we highly recommend following this instruction.
One of our aims is to set the bar higher for the industry as a whole in Europe; by giving our competitors something to aim for too, we hope to ultimately improve the level of professionalisation, quality and safety across the board.
