Grodan Sheet of 98

Grodan Rockwool is made from molten rock spun into cotton candy-like fibers and then compressed in to cubes, blocks, or slabs. These convient cubes can support small to medium size plants from start to finish. They are often used in comination with slabs.

Made in Denmark since 1969, horticultural stonewool is widely recognized as an ideal growing substrate. Each Grodan A'Ok Starter Plug has a pre-formed hole to insure easy seed or cutting placement. Gardeners simply wait for plant roots to penetrate the bottom of each A'Ok Starter Plug before transplanting them into a larger stonewool cube or block. Grodan stonewool is known for its quality, consistency and performance. This is a single sheet of 98, one-and-a-half-inch plugs.
