I used to use these for backgrounds in my dart frog tanks. They are perfect for epiphytic plants and some of the pickier Utrics like U.quelchii and U.campbelliana would do very well on them. They hold moisture far better than tree fern panels without remaining too wet. They stopped making them a few years ago and I was planning on making some of my own. Are any of you familiar with these ? From what I remember they are made of coir that's held together with some sort of latex type product. If any of you have any input on the composition of this product, I'd appreciate it.
