Description

Grodan 713015 Classic Slabs is considered a wet slab due to its horizontal fibers. It holds more water than other slabs and can support more plants than any stonewool slab. Best for hot or dry climates. 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.
