Greenleaf Nutrients Organic Sea-Kelp Powder for Plants – Concentrated Seaweed Extract

Overview of Sea-Kelp Powder

Greenleaf Nutrients Sea-Kelp powder is a concentrated extract derived from multiple kelp species, including Ascophyllum nodosum, Sargassum, and Laminaria. Using a low-temperature enzymatic hydrolysis process, it preserves a broad range of bioactive compounds while delivering a light brown, highly pure powder. This form is 100% water soluble, making it compatible with a wide array of growing systems—from greenhouse drip irrigation to hydroponics, coco coir, peat, soil, and rockwool.

Formulated to support vibrant growth and plant resilience, Sea-Kelp delivers essential minerals and natural growth regulators that plants can uptake with ease. Its high potassium content (over 18% soluble K) is complemented by magnesium, calcium, iron, and other trace elements, contributing to stronger color, structure, and overall vitality in many crops.

What makes Sea-Kelp a versatile choice

Sea-Kelp’s nutrient profile includes polysaccharides and plant hormones such as cytokinins, auxins, purines, and IAA. While the product does not claim to cure conditions, these components are associated with improved vigor and potential improvements in fruiting, flowering, and tissue health under varying conditions.

Key certifications demonstrate a commitment to organic-focused farming: OMRI and EU ECOCERT dual organic certifications for use in organic farming and crop production in the USA and Europe. The product is EPA-compliant and does not contain pesticides or synthetic plant growth regulators. It is designed to be safe for crops intended for human consumption, with regulatory considerations noted for certain regions.
