Hey, the chopstick is a neat trick. I have some bamboo skewers I can use.
Also pick up the pot when you water. Get accustomed to the weight when the chopstick shows it needs watering. As well as the weight right after it watered. Once you get used to it, you should be able to tell my the weight of the pot.
I'm not sure about waterin once a day though. Unless its potted in gravel or something!
