What do hormones/growth regulators contain?

Acadian Seaweed Extract

Ingredients: cytokinins in form of BAP, vitamins and minerals, macro and trace elements, carbohydrates and alginic acid
Uses: can be used for seed treatment, transplant treatment to prevent root shock and at each stage of growth through the plants life.
