The details
RAW Kelp is a
99% pure, water-soluble extract of Ascophyllum nodosum seaweed
. Clean, concentrated, and convenient, it provides a natural source of trace elements and organic compounds widely used in agriculture to support soil and crop management.
Expanded Description:
Kelp has long been valued by growers as a versatile agricultural input. In soluble form, it is
often used to supplement nutrient programs
, improve application flexibility, and provide a clean alternative to bulky liquid kelp products.
Key Features:
Concentrated & Soluble
– lightweight dry powder, mixes instantly.
Natural Source
– derived from Ascophyllum nodosum seaweed.
Flexible Application
– suitable for soil, coco, hydroponic, or foliar use.
Program Friendly
– integrates easily with any feeding schedule.
Biostimulant Synergy:
Many growers choose to combine RAW Kelp with RAW Humic Acid, following the
Virginia Tech–researched 5:2 humic-to-kelp ratio
, a widely recognized approach for maximizing efficiency in feeding programs.
RAW Kelp is available in multiple sizes, up to 25 lbs, making it practical for both small gardens and commercial farms.
For more insight, watch agronomist Harley Smith’s video below, where he explains how kelp can be used as a
seed soak, root drench, or foliar spray
in modern cultivation practices.
