Grodan Plantop propagation blocks are engineered to provide optimal conditions for seedling development in professional horticulture. These blocks are crafted from high-quality stone wool using Grodan’s NG2.0 technology, featuring an advanced hydrophilic fiber structure that ensures precise and uniform water distribution throughout the block. The unique design of Plantop blocks supports excellent water retention and drainage balance, which is critical for nurturing strong root systems during the propagation phase. This balance minimizes water stress and ensures that seedlings receive consistent moisture and nutrient supply, promoting healthy growth and faster development. But if you are a grower who wants to expand further, then you might want to take a look at the Grodan Vital or the Grodan Delta NG2.0.
