X-Fibre Rockwool slabs are 36” long and come in 3 different widths, 6”, 8”, and 12”. Normally, you would place a rockwool cube on top of them and let the roots grow into them. They are great to cut up into squares and use them for the extra root growth below cubes and to keep the plants from tipping over.
