Silica Blast is a beneficial nutrient supplement to be used in conjunction with Botanicare nutrients or your preferred standard nutrient program. It strengthens your plants stems and stabilizes the pH in recirculating hydrogardens. Silica Blast is ideal for use in container gardening or soilless hydrogardening applications. The silicate in Silica Blast encourages the formation of a silicate matrix which reduces transpiration and may allow plants to continue photosynthesis in adverse growing conditions.
