GRODAN GRO-SLABS™ are particularly good for growing large vine crops such as tomatoes or cucumbers. The 36" x 6" x 3" GRO-SLABS are comprised of vertical fibers, which allow for faster drainage and a drier slab. Slabs come in biodegradable UV-resistant poly sleeves which prevent algae, minimize evaporation, and prevent roots and diseases from moving easily from slab to slab. 12 case.
Gro-Slabs™ provide the final stage for growing a spectacularly large plant. Transplant your Gro-Block™ plant onto a slab just like professional growers. They come in clearly marked biodegradable UV resistant sleeves for comfortable handling and algae prevention. With the Uni-slab, all plant roots are protected and contained for the life of the plant.
