Choosing a shade cloth:

Generally for growing plants a shade fabric between 30% and 70% is sufficient. You have to balance shade protection with allowing enough light to get through to your plants which is all dependant on what crop you are growing and whether the plant is a shade loving or sun loving crop. The percentage of shade refers to the quantity of light that is blocked so a 60% shade fabric will let 40% of the light through.

As a basic guide on crops you should use a low percentage shade cloth such as 30% for sun-loving crops such as tomatoes and peppers in areas with hot summers. For colder temperature crops such as lettuce and spinach use 50% - 70% in hot southern areas and 30-50% in cooler northern zones. We advise you to look up the plants you are growing to determine which shade cloth is best for your area.

For non-crop usage for example shading pets, livestock, patios and fencing you might consider a higher level of shade for example 70% - 90% depending on your climate.
