I have an offer of green some glass panes to build a greenhouse. However, they have a green tint. Will they still work, or not? I am in Colorado, so the sun is quite intense. Maybe cutting out some of the solar radiation would be an advantage. On the other hand, maybe they would cut out so much light that seedlings would get all spindly.

The big question would be, does the increased UV at your altitude compensate for the attenuated transmission through the glass? The only way you are going to find out is to do an experiment. If you go half tinted and half untinted, then you'll be on your way to the answer. It also may be that some plants do better with the tinted and others do better with untinted. Have you had problems with sunscald in the past?

I have heard, and read, though I know of no true experiments involving it, that green glass-because it is the same color as leaves-will be absorbing it's opposite which is red. With a lot of the red spectrum absorbed, your plants suffer from a spectrum deficiency of sorts. But like I said, this is hearsay--no science. But you might want to do a google search and explore for some science. Surely it has been studied somewhere. But like John said, maybe your best bet is to try an experiment yourself, and get some science of your own.
