Kelp Blend Trio (Soluble Powder)

Multi-Species Seaweed Extract • Fully Soluble • Organic Plant Biostimulant

A powerful blend of three ocean-harvested seaweeds—Laminaria, Sargassum, and Ascophyllum nodosum—our Kelp Blend Trio (Soluble Powder) delivers concentrated nutrition and natural plant hormones to boost soil health, root development, and plant vitality across all growing systems.

Sustainably sourced from pristine marine environments and processed for complete solubility, this powdered blend dissolves easily in water and is ideal for use in foliar sprays, soil drenches, hydroponics, fertigation, and compost teas.

🌿 Why It Works

Laminaria
Rich in NPK and trace minerals, Laminaria supports robust early growth and energizes soil life. Its natural alginates improve moisture retention and soil texture for stronger roots and better nutrient uptake.

Sargassum
Packed with diverse growth regulators, Sargassum triggers explosive plant growth—from lush foliage to heavy flowering and fruiting. It also enhances soil structure and nutrient availability.

Ascophyllum nodosum
Harvested from cold North Atlantic waters, Ascophyllum delivers a potent blend of auxins, cytokinins, and micronutrients that fuel plant metabolism and increase resilience to stress, drought, and salinity.
