I ended up giving up on using the suction cups and instead drape the plants over different pieces of decor just above the ground. It's hard to describe but I was able to create essentially covered walk ways (or crawl ways I guess ) that my BP uses to move between hides during the day. I used suction cup plants to create a background when I kept mine in a glass enclosure, but when I switched to PVC I didn't have much luck in getting them to stick. Ended up working out though, I like the way it looks a lot more now than I did with them hanging from the walls.
