What PPFD do different plants need?

Leafy greens: 200-400 μmol/m²/s; fruiting vegetables: 400-800; cannabis: 600-1000+. Low-light plants: 50-150. Exceeding light saturation points wastes electricity.

What is DLI and why does it matter?

Daily Light Integral = PPFD × photoperiod hours × 3.6. Tomatoes need DLI of 20-30; lettuce 12-17. Insufficient DLI limits yield more than most other factors.
