Which shade material should I use?
You can use shad net material according to your crop. Those shade material helps protect livestock, pets, plants, and people from direct sunlight and also works well as a privacy barrier or windscreen. Experience has shown that growers use mostly 50% to 60% density, with the high densities of 70% to 80% used in southern states and for light-sensitive plants in northern states.
Many people find that using a high density shade on roofs and a lower density shade on walls is a good method for creating ideal shade conditions. Vegetable gardeners should check with their local University Agricultural Extension office to determine the shade cloth density that is appropriate for both the climate and plant variety.
Shade density is determined by the percentage of light blocked by the shade. For example, the definition of 80% shade is that only 20% of light passes through it. A sunshade net percentage of 30 to 50% is ideal for vegetables, while 80 to 90% is ideal for protecting people.
