Grodan Gro-Slabs

Gro-Slabs

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.

Uni-Slab

If your time is limited and you wish to simply hand water twice a week or if you have never used a GRO-SLAB™ and want to experiment with a small one first, then the UNI-SLAB™ is for you. The UNI-SLAB offers a low-maintenance, simple way for growers to have fresh herbs, healthy greens or one larger plant in a small area. By keeping the wrapping on the stone wool, nutrients and moisture last longer by slowing the evaporation process. The best part of the UNI-SLAB is that it is self contained. So if growing one large plant and disease occurs, the roots won’t spread the disease to other plants.
