Each sheet of Grodan Stonewool A-OK Starter Plugs is perfectly sized to fit a standard flat and each plug has a preformed hole to easily plant seeds and cuttings. Once plants have rooted, gardeners can transfer individual A-OK Starter Plugs to larger pieces of stonewool or plant them directly in soil. For any growing application, stonewool offers speed, ease of use and cleanliness.
