Humboldt Nutrients Ginormous - 0-18-16 PK Supplement - 5 Gal

Phosphorus and Potassium for Bloom Feeding - 5 Gal

Flowering plants draw heavily on phosphorus and potassium, and a base nutrient alone may not always cover that demand. This PK supplement adds both macronutrients on top of your regular feeding program. It carries a 0-18-16 analysis, with 18.0% available phosphoric acid (P2O5) and 16% soluble potash (K2O), derived from monopotassium phosphate.

The 5 Gal container suits growers who feed regularly through flowering, whether in a dedicated indoor room or across several hydroponic systems. If you only need a small trial amount, this size is better suited to ongoing use than a first test.
