The Heavy 16 Veg A & B formula embodies years of plant production experience and nutrient chemistry. Its ultimate function is to begin the process of achieving bulletproof crops with larger vascular systems and structural integrity to ward off pests and support Heavy fruit loads in the bloom cycle. Understand the fact that both under and over-fertilization are detrimental to your plants (and microbes) even when the visual appearance is good. Heavy 16 chemistry helps to eliminate these imbalances and create a platform to get creative but stay buffered. With non-diverse, non-balanced and non-buffered nutrients this is a major concern, and often misunderstood when things look great right before your plants get crushed by fungus, pests, heat, or larger additive and hormone dosages later in the bloom cycle. For rapidly growing crops, now achievable through superior horticultural equipment, this will only compound this law of plant science. Heavy 16 balanced and diverse vegetative nutrients address intense cropping systems collectively with cellular structure and tissue integrity at the core of what we are talking about. Think of plant cells and tissue at the molecular level in leaves, shoots and roots. Now think of the microscopic holes that will happen when minerals are unavailable in the building process.
