The Multi series Soil Blockers are used standing upright. Great for market growers and those gardeners who want to eliminate the use of plastic in the growing process. Create 20 1.5 inch blocks without bending down. Perfect for commercial market garden applications. Push into a wet soil mix, and when the handle is squeezed, out pop identical soil blocks. The Multi 20 Soil Blocker produces twenty 1.5″ cubes that are ready to receive large either seeds or the 3/4″ soil blocks from the Micro 20. When the seedlings are ready, pot them on into the 4″ soil block produced by the Maxi 1. Unit stands 78cm tall. We suggest following the recipe below when using soil blockers.
