Cole, last year you mentioned cheaper low tunnels if I recall. You might be interested in these. $1,250 for a 14' x 100' with a 7'8" peak.Given the quality materials, I don't know if you can build it cheaper yourself. Watch the video to see how it works.
I ordered 2 and its free freight. They qualified for my FY2017 NRCS high tunnel grant.
I'm gonna grow day neutral strawberries under them this year.
