Upside down ?

Maybe more growth in size, rather than encrusting all over a rock base like they typically do before they sprout up and out?

Hanging sps will be benefit lot with it focusing allot on growing then encrusting . We have tried it and had great success. There is quite a bit of info if you type in on google . It's pretty dope
