Nutrient dose to raise a reservoir to a target EC.
The EC shortfall times the tank's liters and a dose factor gives grams of nutrient concentrate to add. Nutrient strength must track plant demand or roots burn or starve, so dosing against EC keeps it in range.
Hydroponic Nutrient
Dose (g) = (target - current) EC x dose factor x liters
Dose (g) = (target - current) EC x dose factor x liters The EC shortfall times the tank's liters and a dose factor gives grams of nutrient concentrate to add.
Nutrient strength must track plant demand or roots burn or starve, so dosing against EC keeps it in range.
This calculator takes 4 inputs: Reservoir, Current EC, Target EC, Dose per L per mS. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
