Our coarse semi-hydro mix is a stable, low-maintenance substrate designed for hydroponic plant care and passive semi-hydro setups. Made from irregular, fired clay particles, it off ers excellent aeration and water-wicking ability without compacting over time. Ideal for plants grown in self-watering pots or LECA-style setups, it helps deliver moisture directly to roots while keeping the root zone light and airy. Unlike regular soil, this mix has no natural nutrients, so fertiliser is crucial in a successful semi-hydro set up. Rinse well before use and enjoy cleaner, soil-free plant care. Show more
