Just a question. Is it best to continue filling with water when it gets low to always maintain it full of is it best to let it get all the way down before refilling?
You don’t necessarily need to wait for the float to go all the way down to fill it again. Just make sure the float would not raise above the garden lid, it would cause overwatering. For e.g. if you’re going away for weeks, you can fill the tank, even if it is half full before filling.
Smart garden 9 float is very reliable. But if you are using a smart garden 3, make sure the float is showing you the correct water level. Sometimes, water gets into the float and it sinks, and, does not work as a water level indicator. Good thing is that it is easy to fix.
