3 Acid Down from Hydropassion. Made from mineral acid, it will enable you to lower the pH of your nutrient solution on a long-term basis and regulate calcium levels. You can use it during the growth and flowering stages of your crops. For use in soil, hydroponics and aeroponics.
An ideal pH value is between 5.4 and 6.5 for your nutrient solutions. Before using 3 Acide Down, you need to know the quality of your water, your type of substrate and your EC level.
Depending on the different periods of your crops, you will need to apply different pH values. During the flowering period, you'll need a pH of between 6.2 and 6.6 to promote the absorption of potassium and phosphorus. For the vegetative and growing period, a pH of 5.6 will allow better assimilation of nitrogen.
