Seed-driver soil blocks can be made to produce healthier seedlings and reduce the need for disposable seed-driver trays and pods. The soil block can be trimmed with natural air to strengthen the root system while preventing tenderness. Plants never become root systems. This can reduce the impact of transplantation, and at the same time can more effectively absorb water and nutrients when the plants are transferred outside, thereby helping you to make the seedlings healthier. Simple operation can quickly make the soil lumpy. Hold it comfortably when you press down and start planting! Natural air pruning helps prevent young plants from forming roots and reduces shock after transplantation. The environmentally friendly solution reduces the need for disposable seed starter trays and pods.
