Grodan Stonewool Growth Slabs MSDSGrodan Stonewool Gro-Slabs
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. Due to its size, the Uni-Slab is perfect for one large plant. Uni-Slab has the benefits of a slab with the versatility of a block. All Gro-Slabs have vertical fibers except the 12 in Gro-Slab, which has horizontal fibers.
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.
Gro-Slabs come in the following sizes:
- Expert Slab - 6" x 3" x 36"
- Expert Slab - 8" x 3" x 36"
- Expert Fat Slab - 6" x 4" x 36"
- Classic Slab - 12" x 3" x 36"
- Uni-Slab - 9.5" x 8" x 4"
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.
What is Rockwool?
Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.
