House & Garden A&B Soil Base Nutrient is designed to be used only in soil or high-quality soil blends. The unique composition of soil particles and existing mineral content requires an extremely precise composition of the fertiliser compounds to ensure that soil and nutriment is used to the full potential.  PRODUCT INFORMATION  House & Garden Soil Base Nutrient is composed of liquid nutrients and trace elements and contains no bulking agents. It is comprised of all essential mineral macro and trace elements and various chelating agents (humic and fulvic acids). These nutrients have been precisely blended to allow for rapid plant absorption.  In short if you want an excellent harvest from your plants in dirt; use House & Garden Soil A&B!  *All A/B Bottles are sold as a pair, e.g. 5L = 5L of 'A' and 5L of 'B'  APPLICATION  When preparing your nutrient container, fill it two thirds with water. First add part A of the nutrient and circulate well before adding part B of the nutrient.  Adjust the pH value to harmonise with the nutrient solution.Do not add A&B at the same time, as this will trigger a chemical reaction in the nutrient, resulting in solidification of some parts of the nutrient and causing incomplete nourishment for your plants.  For best results always follow the H&G Feed Charts available online or at your local retailer.
