Premier Horticulture PRO-MIX BX Growing Medium

Yes, this is an excellent choice for seed starting. Its lightweight texture and balanced moisture retention provide the gentle environment young seedlings need to establish their first roots.

Mycorrhizae are beneficial fungi that colonize plant roots, effectively extending their reach. This helps your plants absorb more water and nutrients from the soil, leading to stronger growth and better stress tolerance.

This product is a growing medium, not a fertilizer. While it contains beneficial microbes, it does not include a nutrient charge, so you will need to start a regular feeding program once your plants have established.

While it is formulated for containers and seed starting, you can certainly use it to amend your garden beds. However, because it is a lightweight, peat-based medium, it is most cost-effective and beneficial when used in pots or for targeted planting holes rather than filling large, open garden plots.

Because this mix is designed with high water-holding capacity, you will likely find you need to water less frequently than with standard, coarser potting soils. Always check the moisture level by touching the top inch of the medium before watering.
