What customers say
This soilless mix earns high praise for its premium quality and reliability, especially for seed starting. Customers consistently value its fine, uniform texture, which promotes excellent seed contact and minimizes early seedling loss. The blend expertly balances moisture retention and drainage, supporting healthy root development. While the initial cost is higher, users find the large volume offers excellent long term value for extensive projects. The mix is frequently noted as being consistently sterile, free from weeds or pathogens upon opening. A minor consideration is that heavy watering can cause slight compaction in small trays, requiring mindful irrigation. Overall, confidence remains high in this mix for achieving robust, successful plant starts.
Know before you buy
Yes, this is specifically formulated for seed starting and propagation. Its fine texture and blend of peat and vermiculite provide the ideal environment for delicate roots to establish.
No, this is a base soilless medium consisting of Canadian sphagnum peat and vermiculite. You will need to introduce your own liquid or granular fertilizer once your seedlings develop their first set of true leaves.
A single bag is quite productive; it will fill approximately 15 standard 1020 seed flats or about 130 standard 4-inch pots.
This mix is balanced for optimal plant growth with a pH range between 5.5 and 6.2, which is ideal for a wide variety of indoor and outdoor plants.
While it is a professional-grade soilless mix, it is not labeled as sterile. However, because it does not contain traditional garden soil, it is significantly less likely to harbor common soil-borne pests or weed seeds.
While it is excellent for propagation, it is a very fine-textured mix. For mature houseplants, you may want to blend it with perlite or coarse bark to improve drainage, as this mix is designed primarily for moisture retention.
