See that's the thing. Its supposed to be the best with UV, moisture... I guess it's an adapted form of polyestester rope. I read that its actually PET. I think if thats true, than there would be no risk of leaching chemicals, but that is really my concern.
Would the hops be able to grip onto a polyester rope? Wouldn't that potentially be too slippery? I mean, it's only got to be durable enough for one season, then rip it down and start fresh the next season.
