Claims that some plant roots click at 220 Hz clicks and that drought cavitation emits ultrasonic bursts above 20 kHz. Builds laser-cut “treehouse” enclosures around an MX chip with a moisture sensor and a speaker, plus a Raspberry Pi mother tree that polls devices at 6:00 and 21:30. Uses the 16 kHz Chirp audio protocol with AES encryption and timestamp to prevent replay. Prototype successfully sends and receives matching packets and displays moisture values on tiny screens.
