Bio-Grow® is a liquid fertilizer that can be applied to most types of soil and substrate mixtures. Bio-Grow® is made from 100% Dutch organic sugar beet extract, commonly known as beet vinasse. Beet vinasse is a by-product of turning sugar beets or sugar cane into sugar. In a natural fermentation process, starches in the sugar are treated with enzymes to produce glucose. In addition to plant nutrients, molasses is a rich source of food for soil microbes, helping to boost populations to create active and productive soils.
