Grow light placement
Use LumaLeaf as a simple grow light meter
Grow lights are easier to tune when you measure the place where the leaves actually sit. LumaLeaf can help compare shelves, lamp distances, and corners by saving lux readings over time.
Compare before changing care
If a plant is stretching, losing color, or drying faster than expected, measure the current spot before moving it. That gives you a baseline to compare after you adjust the light.
Measure consistently
- Keep the phone at similar height and angle for each comparison.
- Measure both the center and the edge of a grow-light shelf.
- Use a dedicated calibrated meter for professional growing decisions.
Turn readings into routines
Save the reading to a plant profile, then use the history and Plant Doctor flow to decide whether a 7-day adjustment plan makes sense.
