GRODAN GRO-SLAB 15 / 75X100 6''x40''x3'' (12)

Most plants can grow in Gro-Slabs but they are particularly good for growing large vine crops such as tomatoes or cucumbers. For plants growing outdoors during mid-day sun Gro-Slabs provide a good water buffer. The 12” Gro-Slab is considered a wet slab due to its horizontal fibers. It holds more water than other slabs and can support more plants than any stone wool slab. The rest of the Gro-Slabs are all comprised of vertical fibers, which allow for faster drainage and a drier slab. Detailed description: - Gro-Slabs - Size of Inches : 6” x 3” x 40” - Slabs/Pack : 12
