Growth & Bloom Enhancement

Heavy PRIME is an ultra-diverse liquid formulation designed for use at all times of your crops’ cycle. We have formulated Prime to be the centerpiece of the Heavy 16 program, but its chemistry allows for flexibility throughout cultivation systems and alternative feeding programs from aeroponics to outdoor soil crops.

Prime eliminates your need for multiple other plant additives that would be considered redundant or incomplete according to our data. Tastes, colors, flavors, and brix levels will all be heightened while expressing the plants true phenotype.
