Rootrainers unique design allows air pruning for optimum root formation.
Better roots mean better plants every time. The grooved cell design directs the main root to grow straight down towards the large drainage opening at the bottom. The root tip makes contact with the air and dies off. The plant then compensates by producing new root growth, with no root balls. Cells open for easy removal of plugs and damage-free roots. Perfect for nearly all plants and especially those that are sensitive to disturbance and require deep root runs. Reusable from year to year. Includes detailed instructions and planting tips.Deep Rootrainers:
