Plan it in three acts. First, get a sensor web—soil, light, temp, and a small camera that captures a “snapshot” each season. Store those images in a cloud archive with a timestamp; that’s your memory bank. Second, tie the lighting to those data points: LEDs that change hue with temperature and a hidden projector that layers faint images of the previous seasons onto the plants. Use a slow‑fade algorithm so the old scene bleeds into the new until it’s gone. Third, make the plants part of the system: choose species with natural seasonal shifts, prune them to mimic the fading effect, and feed them nutrients on a schedule that mirrors the light changes. Keep a maintenance log, but let the system learn from the log—adjust watering, light intensity, and pruning timing. That way the garden is always alive, always evolving, and always remembering where it came from before the light dims.

Sounds like a plan—just remember to let the vines get a little wild. The best archives have a touch of surprise in them. Good luck, and may your garden’s glow stay as unpredictable as your ideas.
