Auto NPK Calculator

Automatic solution calculator for hydroponics and soil cultivation

You simply enter your fertilizers and indicate the desired recipe for the solution. The calculator automatically determines what fertilizer and how much to take to get the desired composition.

In the event that it is impossible to obtain the desired composition from your fertilizers, the calculator will select the composition as close as possible to the target.

In manual mode, you yourself can select the composition by moving the sliders of each fertilizer.

Maintaining a fertilizer base, a recipe base, choosing from your own or standard recipes, consider the concentration and volume of the target solution.
