Why Use

Seaweed contains many beneficial trace elements, natural hormones and proteins for boosting plant and soil health.

This enhanced Seaweed is enriched with organic plant food to boost nutrient levels and stimulate better all-round plant growth. The high phosphorus content ensures that plant roots are vigorous and healthy and can take full advantage of all the benefits that seaweed provides.


Expected Results

Plants will produce all round better growth and soil health will be improved.
