Light-Mix? is the ideal substrate for organic farmers who wish to have control in the growth of their plants through the application of liquid fertilizers (from the very beginning). For any kind of plant, including heavy feeders, larger quantities of fertilizers may be given on demand without the fear of overloading the soil and causing a nutrient burn. Micro activity is created as the liquids work with the substrate to produce organic catalysts. Light?Mix? is also ideal for cuttings, young plants and seedlings.
