Mills Top Mix

Mills Top Mix is a premium, ready-to-use potting soil crafted by Mills Nutrients, combining a carefully balanced blend of black, brown, and white peat with roughly 15 % perlite to ensure loose structure, excellent drainage, and optimal root oxygenation. Enriched during production with a built-in fertilizer formula, typically an NPK ratio around 14‑16‑18 plus added calcium nitrate, this substrate supports vigorous early-stage growth straight from planting, with an EC of approximately 1.2‑1.4 to kickstart healthy development. Its design releases water and nutrients gradually, reducing the risk of compaction and allowing growers to start feeding later with their preferred nutrient line. Mills substrates and nutrients are a great solution for providing your plants with the support they need to grow. So don’t hesitate to check out their Organics Base or the Mills Seed Starter Kit.
