Automated Herb Plant Watering System

Objective

Ok, I admit it: I generally excel at killing plants largely due to neglect. Sure, I could claim work, cooking, hobbies, etc. If I’m honest, I generally forget to water them. So, I wanted to implement an automated watering system linked to home automation. I wanted to do it on the cheap. This was also a test, so if needed a throw-away experiment. Turns out it works for few (3) herb-plants that I needed to keep alive.
