Advanced Nutrients Sensi Grow is a high quality 2-part grow nutrient. Designed by top scientists to be the ultimate product in plant nutrition. Designed by a team of top scientists dedicated to making products of excellence Manufactured to the highest possible standards by Advanced Nutrients Especially made for the vegetative cycle in a plant?s life Perfect for use with the range of Advanced Nutrients additives and boosters How Advanced Nutrients - Sensi Grow A B works: Advanced Nutrients Sensi Grow A B is a base nutrient for all types of hydroponic systems. Advanced Nutrients Sensi Grow A B is complete plant food supplying all the basic nutrients required by plants for strong, healthy growth in the vegetative stage of the plants development. Scientific research and development has made Sensi Grow quite different to other hydroponic nutrients on the market today. For example, Sensi Grow contains an organic ?wetting? agent to allow easier spreading and uptake of nutrients by roots. Sensi Grow also contains humic and fulvic acids for better nutrient absorption and transport around the plant. Finally, Sensi Grow contains a whole range of amino acids which are the building blocks of proteins that enhance growth, hormone production and essential oil production. As if that wasn?t enough, Sensi Grow is now an extremely appealing product to growers due to it?s ?pH perfect? properties. In other words, Sensi Grow automatically adjusts the pH of your nutrient solution to the perfect level and then keeps it there! The saving in time and hassle that this brings is considerable and makes Sensi Grow the easiest-to-use 2-part nutrient available. The only thing you have to remember is that for the ?pH perfect? technology to work, only Advanced Nutrients boosters and additives should be added to the reservoir. Using products made by other manufacturers will stop the pH perfect technology from working. How to use Advanced Nutrients - Sensi Grow A B: Fill your recirculating hydroponic system reservoir with water and add equal amounts of Advanced Nutrients Sensi Grow Part A and Advanced Nutrients Sensi Grow Part B to the tank to achieve the required strength and mix well. We recommend using a syringe or beaker for accurate measurement of this product and a CF/EC/PPM meter such as the Bluelab Truncheon to check the TDS. Adjust as necessary. Next, add any additives and boosters you wish to use and again mix well. As long as you have used only Advanced Nutrients products in your reservoir then the pH will be exactly right. If you have used any products other than Advanced Nutrients then the pH perfect technology will probably not work anymore and pH adjustment will become necessary. Both parts of a 2-part nutrient are designed to be used together in equal amounts. Using only part A or part B, or using them in unequal amounts will result in a nutrient solution which is not properly balanced. This will almost certainly lead to your plants suffering from deficiencies. As with all nutrients, boosters and additives, never mix them together in their concentrated form (i.e. straight out of the bottle). Always add each nutrient, booster or additive to your reservoir or feed water in turn, giving the solution a good stir to mix it in before adding the next one.
