Haxnicks Deep Rootrainers

Grow healthier plants with stronger roots with these Haxnicks' Deep Rootrainers. Deep Rootrainers implement a grooved-cell design, directing new roots downwards, towards the container’s drainage opening. “Air-pruning” design allows roots to die as they hit the air, promoting optimal root formation through healthy, new growth. Rootrainers can easily be opened for moisture and root-progress observation, as well as for safe and easy plant removal. Perfect for seed starting and seedling growth, year after year.  Features 8 "books", which make up 32, 5" reusable cells. Comes with a holding tray, and a propagating lid. 14.17"L x 8.66"W x 3.54"D.
