Shedding Light on Microgreens: A Comprehensive Guide to Microgreens Lighting Requirements
Microgreens require ample light for healthy growth. The best light for microgreens is full-spectrum, mimicking natural sunlight. Focusing on wavelengths of blue (440-470nm) and red (640-680nm) is crucial for photosynthesis. Light intensity, measured in photosynthetic photon flux density (PPFD), should be around 200-400 µmol/m²/s. A photoperiod of 12-16 hours daily is recommended for optimal growth.
