✔ Auto/Manual Power-Off – Conserves battery life when not in use
Why Light Monitoring Matters:
PAR (400-700nm) is the spectrum plants use for photosynthesis - too little slows growth, too much causes stress.
DLI measures total daily light energy - critical for adjusting grow lights or sunlight exposure.
Essential for indoor farming, hydroponics, greenhouses, and horticultural research.
