How to read LED grow light parameters

• PPF (µmol/s) – total usable light for photosynthesis
• PPFD (µmol/m²/s) – light intensity at plant canopy level
• µmol/J – energy efficiency
• PPFD per price – real economic value

FAQ – LED grow lights

What PPFD is optimal for indoor growing?

Most indoor plants perform best between 600–900 µmol/m²/s, while flowering plants may benefit from 1000–1200 µmol/m²/s.

Are watts important when choosing an LED grow light?

Watts alone are misleading. Always focus on PPF, PPFD and efficiency.

Do UV and IR diodes matter?

Yes, when properly balanced, UV and IR can support plant development and flowering.
