I have concerns about polycarbonate because it contains Bisphenol A which is implicated in causing cancer, see: http://www.enviroblog.org/2008/04/cheatsheet-bisphenol-a-bpa.htm. Does anyone know of a closer source of glass geodesic dome greenhouses?

I am researching green houses. Your post allowed me to realize how the angle of my glass will play a key role. With this said, as I construct my green house I will now locate my roof glass as perpendicular to the summer sun as possible, and my south facing lower glass as perpendicular to the winter sun as possible. I also had not considered our lizard and frog friends as being beneficial to our indoor garden, however, in winter they do go into hibernation here, but if inside the warmth of the greenhouse maybe they will not sleep quite as long as usual.
