A sustainably produced kelp biostimulant from Alaska
Alaskan Giant Kelp (macrocystis pyrifera) is the fastest growing and largest species of kelp found anywhere on planet earth. We sustainably harvest our Alaskan Giant Kelp from pristine kelp beds in Alaska. That means naturally higher concentrations of beneficial plant compounds and almost no contaminants or heavy metals.
Alaskan Giant Kelp naturally contains compounds that boost root development and root mass, while also feeding the soil microbiome. Our proprietary extraction process preserves the full spectrum of these bioactive compounds, helping your plants to grow bigger and stronger roots while also creating healthy, living soil.
Growing in intense marine environments Alaskan Giant Kelp naturally produces beneficial compounds that help with plant stress tolerance, especially against heat, drought, and environmental extremes.
KelpEdge has consistently demonstrated improvements to plant yield, harvest quality, and harvest weight through multiple independent trials, and has been validated by some of the countries leading agricultural universities.

The Bridge Between Soil & Plant
The Bridge Between Soil & Plant
Many fertilizer nutrients never reach your plants. They leach through the soil or remain chemically bound at the root zone. KelpEdge™ addresses this through its natural polysaccharides and bioactive compounds which serve as a prebiotic substrate that feeds the beneficial microorganisms in the soil. As these microbial populations grow, they convert bound minerals into plant-available forms, making your existing fertilizer inputs work harder with less waste.
The amino acids and plant growth hormones in KelpEdge™ directly stimulate the production of vital plant defense and growth metabolites. This biological signaling allows the plant to allocate more energy toward rapid development and natural stress resistance. By strengthening these internal pathways, KelpEdge™ ensures your plants remain healthy and productive throughout the entire growing cycle.
KelpEdge™ improves nutrient uptake to make your existing fertilizer more effective.
Our formula reduces the need for excessive chemicals by maximizing every application.
Regular use supports long term soil health and builds natural plant resilience.
