2×2 ft (60×60 cm) Grow Tent Light Guide — 115–150W LED & PPFD
Lambertian simulation with effective Mylar wall reflectance (50%) across a 60×60 cm (0.36 m²) floor. No guesswork tables and no brand bias.
- Fruiting LED: 115–150 W (~570 µmol/m²/s · 16 h)
- Herbs & Greens LED: 95–100 W (~300 µmol/m²/s · 14 h)
- Floor area: 0.36 m² (60×60×160 cm)

Arranging mixed species in this tent
Use the natural PPFD drop-off from center to corners: place light-hungry fruiting crops (tomato, pepper, strawberry) directly under the center and herbs or shade-loving houseplants near the edges.
