Ph-de Bio-Nova is a product with 24.5% phosphoric acid, a relatively low concentration to make life easier. The acidity level of the nutrient mixture is measured after adding all the products. If it gives us a result between 5.5 and 6.5 we can leave it that way, if the level is above 6.5 we will have to add Ph-de BioNova little by little to reach the desired value. If the value is less than 5.5 you will have to use Ph + from Bio Nova.
Now you can lower the Ph level of your water to irrigate, with Ph-de BioNova regulatory liquid. When we use this product, we will not have great changes in the Ph when we work in Hydro or in deposits. A product, which will leave the pH of your nutrient solution stable, and that will not have fluctuations in the levels, at least drastic increases or decreases that can end our crop.
