PK Heavy

Promotes bigger yield & weight

1L, 5L, 20L, 200L, 1000L

A targeted early-to-mid flower additive blending phosphorus, potassium and triacontanol to initiate flower development and stimulate yield — a faster, more uniform onset of bloom across hydro, coco and soil.

PK Heavy

0-6-8-0N-P-K-S (0.0 - 6.4 - 8.0 - 0.5)N-P2O5-K2O (0.0 - 14.8 - 9.7)
Derived from: Phosphorus, Potassium, Triacontanol, Zinc EDTA, Iron EDTA
Application Rates
Early flower: 0.5 mL/L

PK Heavy contains a blend of phosphorus (P), potassium (K), 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.
