The UNI-SLAB combines all the benefits of our traditional slabs with the versatility of a block. Great stability for any size plant.
The UNI-SLAB is completely wrapped thus keeping all the roots of your plant safely contained within the slab, protected from light and outside contaminants. Yet it's small enough to be maneuverable, allowing your plants to be spaced as the plant canopy requires. The UNI-SLAB is suitable for both top drip and flood systems.
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 rockwool, 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.
