Hardly. I don't know how that northern exposure allows for any plants. Perhaps she doesn't grow plants in that room.
There are probably ten's of thousands of "Florida-Rooms" and many more than that throughout the rest of the south. There are excellent glass options available that not only reduce heat penetration (infrared) but also eliminate the vast majority of UV. I may have to use Aluminet in the late spring and summer. Only time will tell, but that's no big deal. It would only be on the 8' deep roof. I would still have 31' Lx8' H glass looking out onto an eastern exposure. This is by far the best exposure to have spring and summer, because it gets morning sunlight but no sun (depending on the time of year) in the afternoon.
