Heavy 16 Prime Concentrate Quart (1L)
Best versatile additive for cultivators seeking enhanced plant quality and vigor.
Heavy 16 Prime Concentrate is an ultra-diverse liquid formulation designed for use throughout your crop's cycle. It acts as the centerpiece of the Heavy 16 program but offers flexibility across various cultivation systems and feeding strategies, from aeroponics to outdoor soil crops. This additive is formulated with carbohydrate complexes, L-amino acids, B vitamins, kelp, natural phyto-hormone derivatives, and high-grade humic acids. It also includes an exotic trace element suite and six forms of potassium, including potassium silicate, to enhance taste, color, flavor, brix levels, and essential oil production. Prime is classified as an engineered microbial feed, a shoot and branch initiator, a sweetener, and an oozer/senescing agent, while also bolstering plant defenses against stress and promoting robust root development. It is primarily organic and can be used in compost teas or complex hydroponic and soil fertility programs.
