I just got a catalog in the mail from Poly-Tex and they've got what looks like an interesting polytunnel/coldframe greenhouse, called a "Kool House", and the prices seem reasonable as well. Does anyone on this forum have any experience with this company? Any idea how easy or difficult this would be to assemble? Also, is there really a big advantage to having a 4' spacing between tubing? A 6' foot spacing is definitely a more economical way to go. One feature I really like that comes with buying a "complete package" is the roll-up sides, which would be great for summer use around here.

I'll provide the link below. I'd appreciate any feedback. Thanks.
