Starter Plugs & Cubes
Seed starting is any gardener’s first step to a successful harvest, and what better medium to get started in than Rockwool? Inert, pH stable, reusable and high in oxygen retaining capacity, Rockwool starter plugs and cubes are an effective substrate to start seeds, cut clones, and vegetate small plants. Unlike alternatives like coco coir and peat moss plugs, Rockwool will not break down and can be re-used through multiple growing seasons. Made from spun molten basalt rock, Rockwool is a unique and powerful addition to any indoor gardener’s grow space. Shop now at HTG Supply for all your Rockwool seed starting needs.
