HPS Reflectors & Fixtures Guide
Your reflector determines how effectively light reaches your plants. The right choice can improve light distribution by 30% or more while managing heat.
- Best for heat management
- Connect to ventilation system

- Glass reduces light 5-8%
- Maximum light to plants
- Best for large spaces
- Requires good ventilation
- Often adjustable angles
- Best heat removal
- Complex setup required
- Used in commercial ops
- Higher maintenance
Reflectivity %
Higher is better. Premium reflectors achieve 95-98% reflectivity using Miro aluminum.
Coverage Area
Match reflector size to your grow space. Larger reflectors spread light over wider areas.
Duct Size
Air-cooled hoods: 6" for 600W, 8" for 1000W. Must match your ventilation system.
Material
Hammertone and textured aluminum spread light more evenly than polished surfaces.
Air-Cooled Hoods
Air-cooled hoods are the go-to choice for grow tents and spaces with limited ventilation. The enclosed glass allows hot air to be ducted away from your plants.
Open Reflectors
Open reflectors deliver more light to your plants by eliminating the glass barrier. Best for larger rooms with proper HVAC or ceiling-mounted setups.
