Humboldt Fulvic Acid Concentrate

Humboldt Fulvic — Organic Fulvic Acid Concentrate

Fulvic acid is the smaller, more bioactive cousin of humic acid. While humic acids improve soil structure, fulvic acids are small enough to penetrate cell walls and deliver chelated nutrients directly into plant tissue.

• Ultra-low molecular weight — penetrates root and leaf cell membranes
• Chelates micronutrients — makes iron, zinc, manganese, and copper immediately available
• Enhances foliar feeding — mix with foliar sprays for dramatically better uptake
• Electrolyte effect — improves ion transport across cell membranes
• Complements humic acid — use Hum-Bolt for soil structure, Fulvic for nutrient delivery

Use as a root drench or foliar additive throughout the entire growth cycle. The perfect companion to Hum-Bolt humic acid.
