Greenhouse Roof

 
 

  The roof of this greenhouse was pretty much rotten, and leaking quite bad.  I tore off the old framing and panels, rebuilt it from scratch, added new polycarbonate panels, and hand-built the operable roof vents. Each roof vent is rigged with a non electric, temperature - controlled opener which opens all the vents at the same time.  (Click any image to enlarge)
