Water-Soluble Powders

HardyGro's water-soluble powder fertilizers and biostimulants offer maximum versatility in application methods and extended shelf stability. These concentrated powders dissolve completely in water for use as foliar sprays, through fertigation systems, or as soil drenches—giving growers flexibility to apply the same product multiple ways depending on crop needs and equipment availability.

This category includes our complete range of biological products: UltraBio mycorrhizae and beneficial bacteria inoculants, protein-based biostimulants like Peptide SP and StressAid, humic and fulvic acid soil conditioners, specialty fertilizers for pre-harvest finishing, balanced NPK formulations, and chelated micronutrient packages. Water-soluble powders deliver the same biological activity and nutritional value as liquid concentrates while offering longer shelf life and more concentrated formulations.

The economics of powder products work in your favor. You're paying for active ingredients, not water weight. A 25-pound bag of water-soluble fertilizer covers the same acreage as multiple gallons of liquid, with less storage space and lower freight costs. Powders maintain potency for multiple seasons when stored properly, unlike some liquid biologicals that have shorter shelf windows.

Mix what you need, when you need it. Whether you're running a large-scale spray program, adding to fertigation systems, or preparing small batches for greenhouse crops, water-soluble powders give you control over concentration and application timing without the constraints of pre-mixed liquid formulations.
