Sea Rock® boasts a powerful plant hormone known as auxin, it is responsible for root and shoot development. Plants absorb water and nutrients more efficiency when exposed to Auxins, improved canopy size and root structure results in stronger faster growing plants.

Ecklonia Maxima contains micro, and macro nutrients, Nitrogen (N), Phosphorus (P) and Potassium (K). The full range of amino acids. Natural growth hormonesauxins and cytokinins which are present, are easily taken up by land plants.

When applied to the soil the quality and structure of the soil improves over time. As this product decomposes vitamins, plant hormones and a broad spectrum of macro and micro-nutrients are released; these nutrients release slowly and are long lasting plant food that promotes soil health.
