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.
