Start Your Gardyn with No Plant Food
Fill the tank with fresh tap water up to the max level. No plant food should be added at this stage.
ON THE 10th DAY: Kelby will remind you it's time to feed your plants for the first time!
Sprouting times can differ a lot from seed to seed—even within species. Move any yCubes that have not sprouted to a tray to help them along and make sure to close all slots left empty.
Top off your tank with water to the max level and add 3 level teaspoons of plant food. You will find the teaspoon in the accessory bag. Kelby will remind you of this, so don’t worry!
FROM THEN ON: Add 1 level teaspoon per 2 gallons of water.
From now on, each time you add water follow this rule of thumb: for every 2 gallons of water added, add 1 level teaspoon of plant food.
