Killing houseplants because generic 'water weekly' advice is wrong
“Every app just says 'water every 7 days'. But my snake plant in winter and my fern in summer are completely different. I overwater everything and they die.”— Hacker News ↗
Apps like Planta hand out fixed schedules, yet over-watering on-schedule is still how most houseplants die. A schedule that adapts to species, season, light, and pot size — and learns from 'soil still wet?' feedback instead of blindly repeating the interval — is the unmet need.

Build an adaptive plant-care app in Next.js. Add a plant (species, light level, pot size, season); generate a tailored watering interval rather than a flat 7 days, and adjust it from user feedback ('soil still wet' lengthens it, 'drooping/dry' shortens it). First 3 steps: (1) add-plant form, (2) an interval recommendation (rule-based or LLM) from the inputs, (3) a 'water today' list + feedback buttons that nudge each plant's interval over time.
