You can apply this liquid growth fertilizer to most types of soil and substrate mixtures. It has 100% Dutch organic sugar beet extract at its base – commonly known as vinasse. This by-product of turning sugar beets or sugar cane into sugar is created by a natural fermentation process. Starches in the sugar are then treated with enzymes to produce glucose that, along with other plant nutrients, help produce a rich food source for soil microbes, boosting their populations for a more productive soil. The natural sugars and potassium in Bio·Grow activate the bacterial flora in the substrate to guarantee you an ample harvest of deliciously sweet fruit.
