Dissolving Plant Food to Top Off Your Tank


Kelby will let you know when it's time to top off your tank along with how much water and plant food to add through a task in the app.

Whenever you need to dissolve plant food to top off, follow these easy steps to ensure your plants get all the nutrients they need - no more, no less! Dissolving your plant food first ensures the nutrients remain bioavailable, or ready, for plant uptake and healthy growth.

1. Dissolve plant food

Place 1/2 teaspoon of plant food in a 1-gallon container, fill with warm (not hot!) tap water, & shake to mix.

  • Tip: Up-cycle common 1-gallon containers, such as water jugs or milk cartons. Just ensure it’s clean before using it!

2. Pour into Gardyn

Remove the small wooden cap to use the watering compartment opening in the lid.

3. Repeat as needed

A full tank has a total of 5 gallons of water and 2.5 teaspoons of dissolved plant food in it. You should now complete your task in the app.

For healthiest growth, keep 2+ gallons of water in your tank at all times

The lower your water level gets, the more your tank's plant food concentration can get off balance. Regularly topping off your tank with fresh water and plant food helps stabilize your tank's plant food concentration, helping your plants thrive.
