Organic Seed Starting Mix

The Organic Seed Starting Mix from PRO-MIX is specially formulated for starting seeds and giving young plants the healthiest start possible. With a fine-texture created from sphagnum peat moss, perlite, and an organic wetting agent, it provides excellent moisture retention and uniform germination. It’s extremely lightweight and airy — supporting delicate root systems and promoting quick, even sprouting. Enriched with an all-natural fertilizer that provides gentle, balanced nutrition, it’s ideal for seed trays, starter pots, or plugs, and OMRI-listed for organic use — making it perfect for growers focusing on sustainable cultivation practices. Once your seeds have sprouted and are ready for transplant, consider stepping up to the PRO-MIX All Purpose Mix for continued support. If you need something for mature plants, the PRO-MIX Premium Potting Mix has added nutrients and a coarser structure that benefits larger root systems.
