it might not be clean in the images, but the tree is at an angle. What i didi is kind of cheating though , but ill tell you anyways. I grew the tree in a pot for a while, and like most trees, it grew vertically, then i trimmed it back down and then planted it at the base of a rock out cropping i made in my terrarium. The terrarium itself is sealed, so the humidity is at about 80-100%. The tree put out aerial roots freely, and i just let them hit the ground and thicken up. The real task is to stay on top of the tree cutting it back and making it o horizontal, this is usually done by wiring branches, like they do with bonsai trees. I keep the tree small by doing what people do with bonsai, i keep it in a small pot. The side that its on has a glass divider under the soil, making the corner its own pot, kind of, restricting the roots and keeping it from turning into a monster tree
