    How old is that screen turbo?

    Interesting thing about the plastic used for those screens, they hate heat!

    No glue will stick to it, so I tried welding that type of plastic once.
    I found that once the plastic became just fluid enough to meld, once it cooled down the plastic became very brittle.

    If you bent it back & forth it would crack after just a couple of bends.

    Yup, that's why hearing it and trying to make sand stick to it doesn't work

    This screen is about 4 years old I think. It started deteriorating about 6-8 months ago, a little bit with each harvest. I'm replacing the whole unit (Rev 1) with a Rev 4 probably this weekend. Way overdue.

    The hole started right in the middle, this Rev 1 has blue LEDs in the middle on each side at full power so it is always photosaturated for the start of the growth cycle. So the screen just got burnt out over time (not literally)

    I assume that is either the effects of heat or UV? however, surely your screen can't get hot enough to make your screen so brittle.

    Since Royal Blue have little to no UV component, I'm guessing it is just the pure intensity of the light. Since it cause photosaturation, the material was more or less constantly exposed to light
