Next to our BioGrow Endo Plus and Pumpkin Power, Joel Holland rates the Soluble Seaweed Powder as the 3rd most important product that helped grow his 2017 World Champion Pumpkin of 2,363-pounds!

Our Soluble Seaweed Powder is the finest available. It is a super concentrated soluble organic product. Now you can get all the goodness of Seaweed without paying to ship water! Each 10.7 ounce packet of powder is equal to 1 gallon of concentrate. This product is OMRI certified organic.


Soluble Seaweed Powder contains a complex matrix of natural plant growth stimulants, including gibberellins, auxins, betraines and cytokinins. These are the factors that influence cell elongation, differentiation, and cell division. Seaweed is also rich in naturally chelated minerals and trace elements, carbohydrates, vitamins, and amino acids. Seaweed also contains primary and secondary plant nutrients. Foliar applications of Seaweed stimulate photosynthesis, resulting in a more efficient production of sugars and starches. Specific carbohydrates in Seaweed cause an increase in beneficial microbial activity, which results in a lessening of pathogenic soil fungi due to competition and physical exclusion. Regular applications to the foliage of plants can induce a systemic resistance against a range of fungi, bacteria, and viruses. Seaweed applications also improve a plants ability to withstand environmental stresses and may reduce the attack and flare-ups of insects, and disease on plants by stimulating the plant to produce phytoalexins and peroxidase.

Seaweed can help plants be slightly more resistant to cold and light frost by increasing the mineral content of intra-cellular plant fluids. Tests on potatoes, using just 3 foliar applications of Seaweed resulted in an increased average tuber weight of 24.2%. 5 foliar applications on seedless grapes resulted in a 31% increase in crop yield and a 21.9% increased average berry weight.
