Convert a ppm nutrient target into grams by volume.
Fertigation frequently works in parts per million, and converting a ppm target to grams for a given water volume uses a volume factor. Reading a target in ppm instead of guessing teaspoons makes feeding repeatable and keeps nutrient levels safe for the crop.
Fertigation Dose
Grams = ppm x gallons x 0.003785
