N-Ext Sea-K Sea Kelp Bio-Stimulant 0-0-5

Concentrated North Atlantic Sea Kelp Bio-Stimulant

N-Ext Sea-K is known in the professional applicator community as microbe food. It is one of the most concentrated sea kelp products available to DIY homeowners, and its quart size covers up to 64,000 square feet at the standard application rate, making it an exceptional value per square foot treated.

Sea-K is derived from cold waters of the North Atlantic and contains high concentrations of Auxins, Gibberellins, and Cytokinins alongside the naturally occurring trace elements and minerals found in kelp. These growth hormones and micronutrients work together to deepen color, increase rooting, improve pest resistance, protect against drought, enhance nutrient uptake, and reduce plant senescence.
