Auxins & IBA

All auxins are hormones, but not all hormones are auxins. The auxin known as IBA (indole-3-butyric acid) contributes to the formation and growth of healthy roots and is the substance in Hormex Rooting Powder. Vitamin B-1 (thiamine) is the additional active ingredient in Hormex Liquid Concentrate. B-1 is a plant growth regulator produced naturally in leaves that moves into the roots to assist their growth. B-1 is always beneficial to plants. By adding B-1 and liquefying its hormone, Hormex Liquid Concentrate promotes thrifty growth at all stages in a plant’s development. Learn more in my blog at
