I’ve got a few of these and never attempted a trellis or moss pole, just letting them trail seems fine. I think they are ground crawling plants rather than climbers. I’m sure you could use a pole, but a basic trellis with really large gaps would probably work better if you want height from the plant. That would probably give you more options for the material challenges you have mentioned too.
What is semi hydro? I’ve got mine in soil, but I’m interested in other ideas.
