Bloom Enhancer

Heavy Fire represents the ultimate hand-crafted P/K booster created through strict adherence to nutritional chemistry and biological principals. Heavy Fire is a versatile bloom supplement that can, because of its ingredients, be incorporated into any existing plant system and nutrient program. Starting Heavy Fire in the last one to two weeks of Veg and going through the entire bloom cycle with a gradual ramp will provide you pre-bloom support and will supply intermediate and late-phase Cascading Delivery of Phosphorous. Also, running Heavy Fire in the late phase of veg can provide for a larger, more resilient root mass, and create larger, and more branched foliage.

Heavy Fire is formulated in a method that brews the material instead of just simply blending it. Natural aging times and subsequent homogenization of both virgin minerals with hand selected ultra-fine ingredients makes Heavy Fire become a chemistry all its own. This combination of ingredients and blending procedures creates a perfect balance between plant nutrition and supplementation from one bottle, allowing the grower to simplify their nutrient regimen while achieving the true quality their plants genetics code for.

With high analysis of P/K equivalents as the baseline, we use three forms of Phosphorous including the highly effective form Phosphite (PO3) as well as three forms of Potassium. Nitrogen is added in the Ammonium form to facilitate Phosphorous uptake and assimilation. We then combine our premium cold processed kelp mix (Ascophyllum nodosum and Laminaria japonica) to supply nutrients that support the natural blooming process.
