PLAGRON HYDRO A+B DETAILED INFORMATION Use and dosage Before use, shake well. For every 1 Liter of water, add 2.5ml of Hydro A (1:400). Hydro A should be used with the same amount of Hydro B. This solution should be used every time you irrigate your plants. These are the characteristics Hydro A NPK (3-0-1 Ca 4.2% MgO 0.4% Hydro B NPK (3-6) MgO 1.4% Hydro A&B: Can I adjust the pH or EC values? When growing 100% HYDRO, it is important to regulate pH and EC. These values are already adjusted by Hydro A&B in their nutrient solutions. Tap water may not have the exact same pH or EC values everywhere. A pH value of between 5.5 to 6.5 is recommended. This can be adjusted with pH Plus and pH Min. Each plant species has a different EC value. To find the best EC value for your plant, use our 100% HYDRO Growth Schedule. Hydro A&B can be stored for how long after being mixed with water. Hydro A&B may be kept in the refrigerator for up to four days once they are mixed with water. The pH value will slowly rise so be sure to monitor it. Organic products can spoil within 48 hours if they are added to the solution. Before you start mixing the solution, make sure the solution is moving properly (circulation pump), and the tank is empty.
