Radikelp SeaPower™ Fresh Kelp Concentrate Unlock the Full Potential of Fresh Ecklonia maxima Radikelp SeaPower™ is a premium biostimulant produced from freshly harvested Ecklonia maxima, a unique brown kelp found exclusively along the nutrient-rich coastline of Southern Africa. Harvested under sustainable permits and processed using our proprietary enzymatic extraction technology, SeaPower™ delivers the complete biological value of the kelp plant in a highly concentrated liquid extract. Unlike conventional extraction methods that separate and discard much of the seaweed biomass, our whole-plant process preserves virtually everything the kelp has to offer. The result is a rich, homogeneous concentrate containing naturally occurring plant hormones, complex carbohydrates, amino acids, minerals and antioxidant compounds that work together to support healthier soils and stronger, more resilient crops.

Why SeaPower™ Is Different


Our proprietary multi-stage enzymatic extraction process is designed to gently release valuable bioactive compounds while preserving their natural functionality. By utilizing the entire kelp plant, we eliminate unnecessary waste and maximise the concentration of beneficial components in every litre.

This unique approach provides growers with a premium-quality biostimulant that delivers consistent performance while supporting environmentally responsible manufacturing.


Naturally Rich in Plant Bioactives


SeaPower™ contains a broad spectrum of naturally occurring compounds, including:

  • Auxins, cytokinins and gibberellins to promote root initiation and healthy plant development.
  • Alginates, laminarins and mannitol to improve soil structure, water retention and plant resilience.
  • Naturally occurring amino acids and trace minerals that support plant metabolism.
  • Phenolic antioxidants that help plants better tolerate environmental stresses such as drought, heat and salinity.

Rather than relying on a single active ingredient, SeaPower™ provides plants with a naturally balanced profile of biological compounds developed by the kelp itself in one of the world's most demanding marine environments.


Benefits to Your Crop


Regular application of SeaPower™ helps to:

  • Stimulate rapid root development and root branching.
  • Improve nutrient uptake and fertiliser efficiency.
  • Enhance plant vigour throughout the growing season.
  • Increase tolerance to environmental and abiotic stress.
  • Support beneficial soil biology and improved soil structure.
  • Promote healthier crop establishment and overall productivity.


Sustainability Without Compromise


Sustainability is built into every stage of production. Fresh Ecklonia maxima is responsibly harvested under regulated South African permits before being processed using a zero-waste extraction system that utilises the entire plant. This not only reduces waste but also ensures growers receive the maximum biological value from every application.


The Radikelp Difference


At Radikelp, we believe that exceptional crop performance begins with exceptional raw materials. By combining sustainably harvested fresh Ecklonia maxima with advanced enzymatic extraction technology, we've created a next-generation kelp concentrate that delivers the complete natural power of the seaweed—nothing wasted, nothing compromised.
