Plagron Promix is a premium peat and perlite-based growing medium for container growers — and this guide covers everything you need to know about how to use it, including dosage guidance, application across the full growing cycle, and an explanation of how the carefully balanced blend of peat moss, perlite, and organic additives creates an optimal root environment for maximum plant performance. Plagron Promix is not suitable for hydroponic or soilless systems, but is ideal for pots, fabric pots, and grow bags of all sizes. Simply fill your containers, add your seedlings, cuttings, or plants, and water — the medium’s excellent water retention and drainage characteristics manage the moisture-to-oxygen balance in the root zone from vegetative growth right through to harvest, while its neutral pH ensures nutrients remain freely available throughout the growing cycle.
