High tunnels side by side = how close together?
I can't fit a long tunnel so I'm thinking two 50 ft tunnels side by side - 14ft wide hoops so is 30ft wide enough (my uncle who is leveling land figured) or should they be farther apart? I was pretty sure they should be farther apart but can't find how far. Again, orientation of land is such that they will be running N-S so I hate to block most of the afternoon sun off the eastern one.
Maybe I can figure posts down the center and do cross bracing and a peak to turn the 14ft wide hoops into a 30ft wide Gothic with 2 bays?
