Cute cute! I wonder how the last one will do with it's leaves going 'north-south' - e.g. will it carry on that way or will it gradually turn itself? I guess a lot will depend on the light source...
There might be a little twist later but I don't think it will matter that much. The reason it's the way it is is due to the roots' position. Rather than cut healthy roots I decided to mount it as you see it.
Very nice mounts and super-cute plants! I agree with your decision to remount #2 in the downward position, much more natrual looking, and now no water spray to stay in the crown!
Good growing - Tony
