Heavy 16 Veg A&B 2 Part Nutrient System




Superior vegetative base nutrient by Heavy 16, designed to create the robust plant infrastructure required to yield voluminous and unrivaled crops.

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’s chemistry helps to eliminate these imbalances and create a platform to get creative but stay buffered.


Veg A: 4-0-1

Heavy 16 – VEG A & B

Heavy 16’s balanced and diverse vegetative nutrients address intense cropping systems collectively with cellular structure and tissue integrity at the core. 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. A simple analogy is that if you keep pouring cement but run out of re-bar, you still pour cement, but that’s the point that will crack first. The plant can still grow and look great to the naked eye without correct levels of key essential elements, but there will be weak points leaving the door wide open for the usual suspects to exploit your plant’s energy. Now add thousands of watts of light input, CO2 at three times ambient, and you get the point. Nutrient availability in proper ratios through balance and diversity is key in today’s most intense grow rooms and greenhouses.

From Heavy 16’s standpoint, it’s all about the Veg, and Heavy 16 Veg A & B is formulated to prove they practice what they preach. Simply put, you want to build beautiful, strong, well-integrated plants with a large root mass in the veg phase so they can take the abuse when you really hammer them in the flowering phase. This makes it imperative that you use Heavy 16 Veg A & B from day one on crop material and mother stock to ensure integrity starts from the beginning and then hit it home with Heavy 16 Bud A & B to finish strong.
