HEAVY 16 Fire, 16 oz (OR Only)

A Phosphorus-Potassium Bloom Booster Built From Multiple Nutrient Forms

HEAVY 16 Fire is a phosphorus and potassium bloom booster formulated to work alongside an existing nutrient program. Starting Fire in the last one to two weeks of the vegetative stage and continuing through the bloom cycle with a gradual ramp supplies pre-bloom support along with intermediate and late-phase phosphorus delivery.

This 16 ounce size combines three forms of phosphorus, including phosphite (PO3), with three forms of potassium and a kelp blend (Ascophyllum nodosum and Laminaria japonica) to support the natural blooming process. Nitrogen is included in ammonium form to help facilitate phosphorus uptake. This size carries Oregon-compliant labeling for growers who need it.
