Lawrence, that's exactly what I did, cut eastern red cedar from my farm, took 
it to a small local guy to cut into 4x5 posts, 12 feet long.  worked great!  
Then we built aluminum framing and put honeycombed polycarbonate on sides and 
top for glazing.  Attached to the south side of the house, automatic vents on 
the top, house windows open in the kitchen to let extra greenhouse heat into 
the house.  We built this on a slope without leveling it because a giant 
black walnut is within 5 feet of the greenhouse.  It's a good one with big 
nuts and I didn't want to cut it down.  The tree provides shade in the heat 
of the summer.  It needs a few tweaks, but all in all, a success. 

Lisa, in the Mo Ozarks
