The ROOT!T Dry Peat Free 24 Cell Filled Tray is a great way to start propagation. And the ideal addition to any standard size propagator. A handy 24-cell tray containing 24 dry peat-free advanced natural polymer rooting plugs which fits most standard seed trays. The unique octagonal cells of the tray ensure a small air gap around the plugs to air-prune the new roots for more rapid development after potting on. The dry plugs are lightweight and can be stored for a long time with no fear of mould development. Simply steep overnight in a water to hydrate before use. The plugs have a stepped dibble (hole) in the top, first a wider hole to accept seed, and beneath that a narrower, deeper hole to accept cuttings. The plugs are natural and biodegradable and will break down naturally into the substrate or soil. The cell tray can be re-used with fresh plugs.
