How you will be feeding your plants. Dosing amounts match this setup.
Start from a recipe
Copy the tank layout, acid dosing tank, ratios, and reservoir/tank volumes from one of your saved recipes.
None of your saved recipes carry a tank layout yet (they were saved before this was tracked). Open one in the Calculator and Save it again to capture this system's tanks, then it'll show up here.
Fertigation System
Growing Medium
Source Water
The readings and nutrient fields below hold the selected test's values, and save as you type. Switch tests or hit + New to start another. The calculator uses the selected one.
Water readings
The descriptive numbers at the top of most reports. Leave 0 for anything not listed.
Measured nutrients (elemental ppm)
From your water report, in elemental ppm (mg/L). Leave 0 for anything not listed.
Trace elements aren't on a standard panel. Add them only if your lab ran them.
Reservoir
Concentrate tanks
Each tank is a concentrate your injector pulls from at its dilution ratio. Keep incompatible salts apart so nothing precipitates: calcium in one tank, sulfates and phosphates in another. You assign fertilizers to tanks in the calculator.
Batch tank
The buffer tank your injector fills with final-strength solution before you irrigate from it. The calculator tells you the total fertilizer in a full tank and how fast your concentrate drains.
