I'm building a trellis to grow my tomatoes on this year, and I used two long maple poles sunk in the ground, connected with very stiff and heavy wire. I've inserted one tall conduit pole in the middle to help support it, and the wire has a turnbuckle on it to tighten it, but it's still not as taught as I'd like it to be. I was thinking about replacing the wire with heavy paracord, since it's so strong, but I was worried because I can't find anyone else talking about doing this online. Is there something I'm not thinking of? Would it be too stretchy? It's supposed to be UV resistant, but I'm wondering how long it would really hold up in comparison to the wire. It's obviously MUCH easier to work with, and I think I could get it a lot tighter with the right knots. What do you guys think? If it works, I'll be sure to post in the Ideas section :).
