Using a plastic saucer or tray to contain soil media, plant a new clone or seedling in the sleeve. When the rooted plant has filled the sleeve with roots, then place the rooted clone or seedling on top of a living soil bedsystem for the life of the plant. After harvest is complete, leave the old sleeve and place the next plant right next the first. When the old roots system is gone, you can remove the old sleeve and re-plant in the original location.
