alt Hacker NewsI'm reminded of that adage "Given the opportunity, players will optimise the fun out of a game". A fully automated setup is cool, but if it's working well, there's not much to do. You're not gardening any more.
I have a bunch of plants on my window sill, and considered getting moisture sensors and automating watering, but I realised that kind of defeats the point of looking after the plants myself. On top of the satisfaction of manual work, I recently realised that it's taught me an intuition - the quirks of how much water each plant wants at different times of year (even cacti are thirsty in summer!), and how soil composition and pot size affects water retention. It's probably not generally transferable knowledge, but it was fun to realise I'd come to know my plants really well.
Th author spent however long on setup and wrote up a blog post. They are doing something different than you, but it’s clear they are also having fun. There is room for two approaches, and I’m not going to tell anyone else their approach “defeats the point,” because we really don’t even have to agree on the point! Glad you enjoy your approach.
