Heavy 16 Fire P/K Booster for Phosphorus & Potassium Support

Heavy 16 Fire is a versatile P/K booster built to integrate into most feeding programs in hydroponics, coco, or soil. It’s crafted by brewing and natural aging, then homogenized with virgin minerals and ultra-fine ingredients for a consistent, uniform nutrient.

Heavy 16 Fire for Late Veg Through Flowering

Begin in the last 1–2 weeks of vegetative growth and gradually ramp through the flowering cycle to provide steady phosphorus delivery through mid and late stages. The formula includes three forms of phosphorus (including phosphite) and three forms of potassium, with ammonium-form nitrogen to help uptake and assimilation. A premium cold-processed kelp blend (Ascophyllum nodosum and Laminaria japonica) contributes naturally occurring compounds that support plant vigor and productive development. This single-bottle approach helps simplify your regimen while encouraging stronger roots, fuller canopy growth, and heavier yields.

Key features:

• Strengthens phosphorus & potassium availability for demanding production phases

• Supports larger, more resilient root mass when used in late veg

• Brewed + aged process for consistent mixing and reliable feeding

• Kelp blend supports overall plant vigor and performance

• Helps streamline nutrient programs by adding targeted P/K support in one bottle
