Whereabouts are you? That will help determine how 'shady' your shade cloth needs to be. The Aluminet I have came in a range from 30% up to 90% as I recall. What you order depends on how strong your sun is through the fall/winter and spring.
You can put your location (city, state etc.) in your personal profile and then it will show up each time you post in the upper right corner. This really helps others a lot when answering your questions.
