I have a new on a lava rock chunk. It’s a work in progress but mostly my fault lol
That's great!
I think I'll try this with a new Neo I got the other day once the aquarium stores open here and I can get some lava rock. The roots are so long I couldn't pot it. I mounted it on some cork bark and put it in a glass vase for now but I'm worried it'll still be too dry in my low humidity.
