I’ve spent a lot of time watching how the sun’s rays hit my seedlings, so the idea that a specific light spectrum could speed healing after a cut isn’t far-fetched. Red and far‑red light seem to push cells into repair mode, kind of like a gentle reminder to grow. It’s not just the wavelength; intensity and timing matter too—too bright and you burn, too weak and you waste effort. I’m a bit wary of chasing a perfect spectrum; plants are stubborn, and they’ll adapt if I keep the light steady and give them time. Still, if you can dial in the right mix, it could be a quiet, effective boost for their recovery.
