This is one of our favourite general use soil mixes. For indoor and outdoor potting and seed starting this OMRI listed mix contains Canadian sphagnum peat moss (60-70%), coir, perlite, calcitic limestone (as a pH adjuster), and an organic wetting agent that ensures good moisture retention and drainage. Certified Organic and Quebec VRAI certified. Plus it contains a mycorrhizal charge, so it is biologically active. This mix keeps its shape nicely when potting on, without becoming clumped up. The drainage is excellent and plants respond well to ProMix Multipurpose Organik. 80L 27.2kg (80 lbs) bag (pick-up only).
