Ladbrooke Soil Blocker Micro 20 produces 20 x 2 cm (3/4 inch) soil blocks with indentations for small seeds. 2 cm (3/4 inch) soil blocks are ideal for seedlings that will be "potted up" into larger soil blocks so they can grow good sized root balls.
Soil Blockers are a fantastic tool for market growers and gardeners who want to eliminate the use of plastic in the growing process. Growing seedlings in soil blocks also allow their roots better access to oxygen and prevents them from being rootbound. Simply push the soil blocker into a wet soil mix and squeeze the handle to make soil blocks.
