Not sure if you can see it in the photo as well as I can see it in person, but I can see the beginnings of a change. The scrap retains the original blue-clear color, but the panels on my greenhouse appear slightly less clear, and more yellow in tone. This is after 7 1/2 months in southern New Mexico sun (intense sun much of the year) with occasional temps over 100°. I'll take more pics periodically to record any progression. |
