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, these propagation plugs offer the perfect balance of moisture, aeration, and stability, helping young roots establish quickly and securely. Substrates keep conditions consistent, making them ideal 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 germination and fast rooting, giving growers the confidence that their plants are starting with the best foundation for vigorous, healthy growth.

We recommend our Plugs & Substrates range for growers who want consistent, professional results at every stage — available now with speedy UK delivery from Greens Horticulture.
