Sure thing. Keep the controller tiny, just enough to read soil moisture and trigger a small pump. Use a low‑power sleep mode, wake up every few hours, maybe even use a solar panel or trickle charger from a nearby stream. Set a threshold so the pump runs only when the soil gets really dry. Add a timer so it only runs during the day to avoid evaporation. That’s it—simple, reliable, and will let the plants do their thing.
