House & Garden Hydro A&B uses unique formulations specifically for run-to-waste hydroponic systems. Hydro A&B allows for rapid nutrient uptake as efficiently as possible. This powerful base nutrient has been designed to provide complete fertigation for both vegetative and flowering (generative) growth. Ideal for run-to-waste systems in rockwool, flock, perlite, clay, growstone, gravels, vermiculite or volcanic stone. Our Hydro A&B base has been precisely designed to provide the complete range of required nutrients in beautifully soluble forms using unique chelating agents. Hydro A&B is engineered to balance optimized pH levels rapidly, resulting in more effective nutrient uptake and faster, healthier plant growth. H&G Hydro base nutrients are produced from 100% liquid base nutrients, not powders. Combined with our unparalleled mixing technology in the USA and incredible zero-waste facility; Hydro A&B is the cleanest and most concentrated base nutrient on the market! Always make sure to test your EC when using our super concentrated formulas, so you can use less for more success! House & Garden Hydro A&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.
