You can use the water level indicating float to monitor the overall water level. When the float hits the bottom and you can no longer bob it up and down with your finger, it's time to refill the tank. The water tank lasts for about 2-3 weeks, depending on the plants, but you can definitely fill up the tank sooner if necessary.
How to avoid overwatering?
The Smart Garden is designed to monitor the water level on its own. However, it is crucial to avoid adding too much water to the water tank.
If you pour too much water inside, the system does not regulate properly - the water level indicating float should not rise higher than the garden surface.
Float is filled with water
It can sometimes happen that due to how the Smart Garden 3 float is assembled, its edges might not align properly.
This can cause a small gap to appear that will allow water to enter the float, making it display an inaccurate water level.
To remove the water you can try to either drain the float, or a faster and simpler solution is to open the float up (which may require some force), drain it and then re-assemble it, while making sure the edges align back together.
