3×3 tent, 9 sq ft, 200–300W — here are the lights that fill this space efficiently
A 3×3 tent (9 sq ft) needs 200–300W of true LED power in flower to achieve 800–1,100 μmol/m²/s PPFD across the canopy. The right light for a 3×3 tent hits that PPFD sweet spot efficiently, fits physically inside the tent, and has adequate hanging height for adjustability.
Target 30–50W actual draw per square foot in flower. For 9 sq ft: 200–300W actual draw. This produces 800–1,100 μmol/m²/s at canopy level with a quality LED quantum board at proper hanging height (18–24" above canopy).
