Plugs & Substrates

Plugs & Substrates are designed to give seedlings and cuttings the best possible start in life. Made from clean, uniform materials such as peat, coco, or synthetic fibres, propagation plugs provide the ideal balance of moisture, aeration, and stability, helping young roots establish quickly and securely. Substrates keep conditions consistent, making them perfect for use in propagators or when transplanting into larger pots and hydro systems.

At Greens Horticulture, we stock a wide selection of propagation plugs, starter cubes, and substrates from trusted brands, suitable for all growing methods. Easy to handle and highly reliable, they ensure strong, even germination and faster rooting, giving growers the confidence that their plants are starting out with the right foundation for healthy, vigorous growth.
