Ready-to-use organic propagation cubes for seeds and cuttings. No soaking, no pH adjusting, no fiddling — take them out of the tray and use them. Why they are easier than rockwool The cubes hold a fixed pH and EC that stays put even after watering, so there is no conditioning step and nothing to get wrong before you start. They absorb water fast and hold a stable water-to-air ratio, which is the balance cuttings need to root rather than rot. There is also a base fertiliser built in, enough to feed a seedling or cutting for its first two to three weeks — so nothing else is needed until you pot on. Made from An organic blend of coir pith, black and white peat, garden and potting soils, bark fines, wood fibres, wood mulch, sand and grit, perlite, pumice, clay and vermiculite. 100% compostable. Specification 77 cubes per tray Cube size: 35 x 35 x 30mm Tray size: 53 x 31cm — fits a standard propagator Pre-formed hole for a seed or cutting Transplanting The plugs stay firmly bonded, so the whole cube lifts out in one piece and goes straight into your medium — the roots are never pulled apart, which is where most propagation losses happen.
