Water-soluble solutions for home growers, professional cultivators, and commercial agriculture.

Soluble Plant Nutrition

RAW KALIX

The Science of Solubles

The plant nutrition industry has never been short on overpriced bottled products. We chose a different approach.


NPK Industries develops highly concentrated, water-soluble fertilizers, supplements, biostimulants, and microbial products designed to give growers more control, greater flexibility, and better value. Why pay for water when you can start with the active ingredients?

Through RAW and KALIX Complete Plant Nutrition, we continue that commitment to clean solubility and reliable performance for growers at every scale.
