I’ve recently contemplated a submersible pump in a bucket (to limit the water in the event of a leak), and just using one of those $10 cloud-enabled switchable plug outlets, with fan-out drip tubing and a suitably-sized flow regulators going to each plant. Eventually perhaps building in some moisture sensors and some pi/arduino logic to then control the pump.
