RootMaker Propagation Trays - 60 Cell Seed Starter Trays for Plants, Vegetables & Herbs | Ideal for Indoor Gardening, Greenhouses & Hydroponics

• RootMakers® are designed to direct roots into openings in the container. The first root to reach an opening is usually the tap root. When this occurs, the tip dehydrates and stops growing and secondary roots form that are horizontal in growth habit. These secondary roots are dehydrated and create additional root branching.
• For best results, it's recommended to use RootMaker® propagation trays on top of a wire bench or other support that allows airflow, 18 to 24” above the floor to allow good air circulation and thus efficient air-root pruning on all sides of the container, not just the bottom.
