Does anyone know if you can use Lexan in a solargreenhouse? I can't find definitive information on whether the uv spectrum the Lexan blocks is necessary for heating. It appears to be fine for plants, but I want the uv rays to passively warm a heat sink, like water or rock.

Cheaper. Look at fiberglass like Kalwall. The lexan is great stuff, just expensive. My father has it on his greenhouse and loves it. I would love to have it but it is outside my budget right now.
