Heavy 16 Fire – 500ml


Heavy 16 Fire is the ideal bloom additive, enhancer, hardener, and finisher. Though this item may be used with any brand of base nutrients, it produces best results when used in conjunction with other Heavy 16 products.


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 stimulant 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 stimulation, and, will supply intermediate and late-phase Cascading Delivery TM of Phosphorous. Also, running Heavy Fire in the late phase of veg will provide for a larger, more resilient root mass, and create larger, more branched foliage. With high analysis of P/K equivalents as the baseline, we use four 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 balance natural blooming hormone levels, bio-clays to ensure natural structural integrity and quality (natural silica and calcium, plus exotic minerals), low molecular weight fulvic acid to allow for natural chelation of elements, and natural plant derived energy boosters to increase flower formation rate and maturation.

Heavy Fire is formulated in a method that actually 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 stimulation from one bottle, allowing the grower to simplify their nutrient regiment while achieving the true quality their plants genetics code for.

When formulating Heavy Fire, we chose to incorporate virgin Phosphite (Phosphonic Acid) for the reason of its optimum availability and its key position in the Cascading Delivery philosophy. Along with the multiple forms of Phosphate in Heavy Fire, Phosphite is extremely mobile and ensures increased root development, bud formation, and stress and disease resistance. Phosphite is extremely mobile within both the xylem and phloem of the plants vascular system allowing it to be rapidly incorporated into biochemical reactions. The true beauty of phosphite is that once it is rapidly absorbed in this streamlined molecular form, it is then oxidized or converted into Phosphate inside the plant, equating to an internal time-released offering of Phosphorous. This allows for a continual presence of Phosphorus for energy transfers and other critical time sensitive functions when the plant is naturally demanding P. As an added bonus, Phosphite will actually function as a fungicide by encouraging nuclei within the plants cells to release natural defense molecules that attack fungal pathogens directly while also adding to the mass of the cell wall.

Core Ingredients In Achieving Fire’s Performance:

  • Phosphite
  • 3 other forms of available phosphorus
  • 3 forms of available Potassium
  • High rates of Phosphorous and Potassium to ensure a significant, high quality harves
  • 2 types of cold processed kelp: Ascophylum Nodosum and Laminaria Japonica
  • 2 forms of Bio – Clay (with exotic minerals)
  • Triacontanol (Naturally derived)
  • Handful of other proprietary plant extracts and organic acids.
