Heavy 16 Fire – 1 Liter

Heavy 16 Fire: Brewed P/K Booster for Late Veg Through Flowering Heavy 16 Fire (1-10-16) is a versatile P/K booster crafted through brewing and natural aging, then homogenized with virgin minerals and ultra-fine ingredients for a consistent, uniform formula. It delivers three forms of phosphorus—including phosphite—and three forms of potassium, supported by ammonium-form nitrogen for improved uptake and assimilation. Multi-Form Phosphorus, Potassium, and Cold-Processed Kelp for Hydro, Coco, and Soil Begin application in the final 1–2 weeks of vegetative growth and ramp through the flowering cycle for steady phosphorus and potassium delivery through mid and late bloom. A cold-processed kelp blend of Ascophyllum nodosum and Laminaria japonica contributes naturally occurring biostimulant compounds that complement the mineral P/K base. Available in 500 mL, 1 L, 4 L, 10 L, and 23 L. Key Features Brewed and Naturally Aged Base: crafted through brewing and natural aging with virgin minerals for a homogeneous, consistent formula Three Forms of Phosphorus: includes phosphite alongside standard phosphate forms for comprehensive P delivery through the bloom cycle Three Forms of Potassium: multiple K sources for reliable potassium availability from late veg through late flowering Cold-Processed Kelp Blend: Ascophyllum nodosum and Laminaria japonica contribute naturally occurring biostimulant compounds to the mineral base Late-Veg to Late-Bloom Window: start 1–2 weeks before flower initiation and ramp through the full flowering phase for sustained P/K support
