Beginning with carefully selected ingredients and formulated by a team of professional horticulturists, the Sunshine Advanced Growing Mix #4 is made from high quality raw materials and provides an ideal growing mix for your indoor and outdoor growing needs.
The foundation of the growing mix is Canadian Sphagnum peat moss, sustainably harvested from carefully managed bogs in rural Canada. The peat moss is screened to remove large clumps and sticks and is blended with horticultural grade perlite and coir (a by-product of the coconut industry). Peat moss reduces the leaching of nutrients from the growing mix allowing them to release slowly over time. Perlite keeps air spaces open while coir combined with peat allows good water retention. This provides a balance of air and water that results in good root growth and the foundation for good stem and flower growth. Dolomitic lime, a starter organic fertilizer, mycorrhizae and an organic wetting agent are added to complete the mix. Lime adjusts the pH for optimum fertilizer availability; the starter organic fertilizer helps transplants establish; mycorrhizae assists in fertilizer uptake and the organic wetting agent helps peat moss absorb water better.
