Shade percentage factors and crop suitability
- 35% to 50% shade factor (Green/Black): High light transmission ideal for vegetable cultivation (tomatoes, sweet peppers, chili) and fruit nurseries.
- 75% shade factor (Green/Dark Green): Suited for shade-loving ornamental foliage, orchids, anthuriums, and ginger/turmeric during hot summer months.
- 90% shade factor: Heavy shading used for vehicle parking, cattle sheds, and extreme desert heat insulation.
- White / Aluminet thermal screens: Reflect excess infrared heat, maintaining cooler interior temperatures in polyhouses.
Factors determining quality and purchase choice
Shade net durability depends on HDPE polymer grade, tape-to-tape vs monofilament knitting, and grams per square metre (GSM, typically 80 to 160 GSM). Always verify that nets are UV-stabilized to withstand intense tropical solar degradation for at least 3 to 5 years of outdoor exposure.
Government subsidies under MIDH
The Mission for Integrated Development of Horticulture (MIDH) and state horticulture departments provide capital subsidies of 40% to 50% of benchmark unit costs for constructing shade net houses and procuring approved quality shade fabrics.

What does GSM signify in agricultural shade nets?
GSM stands for Grams per Square Metre; higher GSM indicates thicker, heavier, and more durable knitted fabric.
Where can farmers apply for subsidies on shade net houses?
Farmers apply through the state horticulture department portal under the Mission for Integrated Development of Horticulture (MIDH).
