The unrivaled 3 part nutrients system consists of a combination of all primary, secondary and micronutrients in three separate formulas: Grow, Bloom and Micro. No synthetic dyes are used in the manufacturing of these products. The colours are naturally derived and are light, heat and acid stable. The product is designed to be seamlessly integrated into any feeding schedule and to replace any current three-part system on the market. The formulation contains no carbonates unlike a number of other products on the market. All of the ingredients are 100% water soluble and are immediately available to your plants. 100% chelated micronutrients with 3 unique sources of iron designed for a broad range of pH environments. Provides more flexibility than a conventional 2 part nutrient system. Does not leave a heavy salt residue due to its low salt index.
