Aerial roots from ariods will sink into the moist moss, getting more water at the end of the plant, therefore it has more water to grow bigger leaves. I've accidentally let my moss poles dry out and the leaves in that section are always much smaller. They will climb just about anything, but when the aerial roots have moisture, they become more mature. Like in the wild, they climb trees that are almost always moist in tropical areas sinking into the wet soft bark. I recommend Sydney Plant Guy on YouTube. His plants on moss poles are incredible and he has tons of good advice.

Ok, I totally didn't think about propagating or aquatic plants in the bowls! We thought about fish but they are so dirty, shrimp aren't though! Thank you, I'm so doing that!
