The primary difference is light transmission:  a 50% shade net blocks half of the sunlight (allowing 50% through), while a 70% shade net blocks 70% of the sunlight( allowing only 30% through). Choosing the right density depends entirely on the heat and light tolerance of your plants or livestock.
50% Shade Net
  • Light transmission: Allows 50% of ambient light to pass through.
  • Best for: General vegetable gardening, young seedlings, hardening off nursery plants, and sun-loving crops that need protection from extreme midday scorch.
  • Environment: Creates a moderately bright microclimate with robust air and light flow. 
70% Shade Net
  • Light transmission: Allows only 30% of ambient light to pass through.
  • Best for: Shade-loving crops (like ferns and orchids), highly delicate ornamentals, and intense low-altitude hot regions.
  • Non-farming uses: Excellent for livestock shading (poultry, goats, and cattle) to heavily reduce heat stress, or for human carports and recreational outdoor covers.
  • Environment: Creates a significantly cooler, heavily filtered, and lower-temperature zone.
