Sustane BOLSTER BIOSTIMULANT is a concentrated plant growth supplement specifically developed to prepare plants for improved growth in sub-optimum and stress conditions. BOLSTER is a scientifically balanced formulation of cold-processed seaweed extracts, humic acid, and plant nutrients, which provide optimum growth potential. Seaweed extract from Ascophyllum nodosum is an excellent source of auxin, cytokinin, and gibberellin hormones and trace minerals. These hormones are combined with humic extracts from Leonardite and a specially chelated iron that is readily available. BOLSTER's performance is proven in years of field research and university testing. Apply with hydroseed at 1 - 2 gallons per acre.
