Step-by-Step
-
Add nutrients only when adding water. Never add nutrients without topping off your tank.
-
Measure carefully – Use the 1-tablespoon scoops included with your Farmstand.
-
Mix separately – Dissolve Nutrient A and Nutrient B in separate jars of warm water.
-
Add to tank – Pour dissolved nutrients into the tank, then top up with cool water.
-
Follow your dosing guide – Reference your weekly email or the Lettuce Grow app for the exact amount of Nutrients A and B to add.
Dosing Example
-
Example: If you’re starting a 24-port Farmstand in spring, add 4 tbsp of each nutrient at setup, then 1 tbsp of each nutrient weekly after that.
-
Missed a week? Double the dose the following week when adding water.
