Advanced Nutrients - Dr. Hornby's Big Bud Liquid is a liquified formulation of his legendary original Big Bud formula. Dr. Hornby's Big Bud Liquid has been extensively researched, developed and field tested. It's specifically designed for medical cannabis flowers, and is uniquely effective when compared to all bloom formulas made by our competitors. During field testing, Big Bud overwhelmingly outproduced all of its competitors, because Big Bud's contains plant-specific ratios of Phosphorous, Potassium, Magnesium and Amino Acids. Big Bud will dramatically increase bud growth, width, weight and resin production like no other bloom enhancing product can.
