Stonewool is recognized the world over as an ideal hydroponics growing medium. Seeds or cuttings are started in these larger Grodan Gro-Blocks and, once rooted, the blocks are transferred to a larger stonewool slab. Gro-Blocks can also be planted directly into containers for soil gardening. Pictured is a strip of six 4″x4″x2.5″ Gro-Blocks, each with pre-formed holes. Grodan stonewool is known for its quality, consistency and performance.
