Kelp contains many wonderful things such as over 70 minerals and trace elements, growth hormones, vitamins, enzymes, and proteins.
The second important and perhaps the most important aspect of kelp is the growth hormones. Kelp contains ample quantities of auxins, gibberellins, and cytokinins. All growth hormones play a part in how a plant functions, and are more accurately called growth regulators. Kelp has very high amounts of a particular hormone, cytokinin. Cytokinins are responsible for cell division, cell enlargement, differentiation of cells, development of chloroplasts as well as a delay in aging.
