The details

Meet your next everyday essential.

RAW Potassium delivers
50% water-soluble potash (K₂O)
derived from potassium sulfate. Clean and fully soluble, it helps maintain potassium levels during peak demand, supporting healthy fruit and flower development.

Expanded Description:
Potassium is often called the
health element
of plant nutrition because it influences overall crop quality more than any other mineral. From nutrient transport to enzyme activation, potassium underpins the processes that keep plants vigorous and productive.

RAW Potassium provides a concentrated, soluble source of K that integrates easily into any feeding program.

Fruit & Flower Quality:
Supports firmness, flavor, aroma, and overall marketable yield.

Peak Demand Support:
During heavy production cycles, plants can draw down potassium reserves quickly. RAW Potassium restores balance fast to prevent deficiencies.

Nutrient Transport:
Improves the movement of sugars, water, and nutrients throughout the plant for consistent performance.

Stress Tolerance:

Flexible Application:

RAW Potassium is ideal for correcting deficiencies, boosting potassium during fruiting and flowering, or fine-tuning custom nutrient recipes.
