This paper presents a human-plant interaction system that helps observe daily mental fatigue levels by enabling the synchronisation of human eye blink data with plant health. We want to facilitate introspection on our subjective well-being by leveraging plants' organic growth as a reflective medium. Based on users' daily fatigue levels assessed from their eye blink data, the system controls the quality and intensity of the grow LED installed on the sensor-augmented plant. Another LED placed in front of the planter also displays the plant's health, combining light intensity and daily average eye blink frequency. We aim to design a novel means to connect human biosignals with plant health and introduce human-plant interaction as a reflection on subjective well-being.
