PK Heavy - Promotes Yield & Weight 500ml Nutrifield

Targeted flower additive containing a blend of phosphorus, potassium, and triacontanol to support plant growth during the early mid flowering growth phase and thereby stimulate yield.

The transition into flowering involves a significant shift in plant physiology: increased energy demand, accelerated cell division, and the formation of reproductive structures. PK Heavy addresses this directly, providing stage-specific nutrition rather than functioning as a generic phosphorus-potassium supplement.

Highly available phosphorus supports ATP synthesis, energy transfer, and cell division, establishing the biochemical foundation for early reproductive growth. Potassium facilitates carbohydrate translocation, enzyme activity, and osmotic regulation, directing photosynthetic output toward developing flower sites. Triacontanol is incorporated at precise concentrations to enhance photosynthetic efficiency and metabolic throughput, supporting accelerated, uniform flower formation without overstimulation.

The outcome is a faster, more uniform onset of bloom, increased flower-site initiation, and improved early-stage density. Within the Signature Range, PK Heavy forms the first stage of the flowering program, working ahead of late-stage inputs such as Crystalic.

Derived from: Phosphorus, Potassium, Triacontanol, Zinc EDTA, Iron EDTA

Nutrifield PK Heavy contains high levels of the macronutrient phosphorous (P), which is a key component of ATP, the chemical energy molecule in plants required to carry out metabolic activities. Flowering is a very energy intensive cycle of plant growth, which places a high demand on phosphorous (P) to fulfil the increased ATP requirement. The boost in phosphorous (P) from PK Heavy stimulates flower bud development, bud set, and blooming. Nutrifield PK Heavy delivers high amounts of potassium (K) which facilitates the internal movement of nutrients through the plant. Nutrients are required as they are the building blocks for flower formation. Potassium is critical for the efficient movement of nutrients within the plant to the flowering sites where they are needed. The boost in potassium (K) from PK Heavy ensures stomata function correctly to prevent water loss and ensure sufficient CO2 is available, as these are critical during photosynthesis.
