grodan gro-slab 15/75 6''x36''x3'' (12)

Most plants can grow in Gro-Slabs, but they are especially useful for large vines like tomatoes or cucumbers.
Gro-Slabs provides a good buffer for outdoor plants on sunny days.

The 12” Gro-Slab slab is considered a wet floor slab because of its horizontal fibers.
It holds more water than other slabs and can support more plants than any wool slab.
The other Gro-Slabs panels are all made from warp threads, allowing for faster drainage and drier decks.
