Organic matter










Natural plant hormones





1.Special growth hormones called cytokinins and auxins act like 'plant steroids.' They're absorbed directly through the foliage and result in larger vegetables; juicier fruits with longer shelf-lives; and fuller crops across the board.

2.Seaweed's plant hormones also work below the surface, stimulating the development of more extensive root systems. This helps to increase water access, resistance to root diseases, and offers protection against wind damage.

3.Alginates are a well-known 'clay improver' and also help to hold water in the topsoil. Meanwhile, seaweed encourages microbes within the soil to convert unavailable nutrients into a form that plants can actually use.

4.Seaweed contains many vital micronutrients that help protect against stress and disease. Alginicacid and mannitol, also present in seaweed, are superb carriers of these elements, taking them straight to where they're needed.

5.Seaweed increases the amount of chlorophyll in leaves, allowing plants to better harness energy from the sun. With more energy plants enjoy stronger growth and appear greener, healthier and more vibrant.
