Grodan 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"
