Durable And Eco-Friendly - Crafted with high quality zinc-coated steel, our soil blocker is sturdy and well built so lasts through years of use - reduce the need for wasteful plastic seed cell trays. Simple Yet Innovative - Quickly make a set of four 2" square soil blocks in one smooth, easy motion. Simply mix and wet your soil of choice, press in using the comfort grip handle, and you're ready to plant your seedlings! Each block well has an extra height - 2.39" to ensure even soil packing and more durable finished cubes. Ergonomic Handle Design - The Manual Quad Soil Block Maker's handle features non-slip cushioning and an ergonomic shape for easy planting, season after season. Better For Seedling - The soil block produced by soil blocker minimizes damage to fragile root systems during transplanting and avoid root binding as the roots are air pruned when they reach the edge.
