GSP wall?

[Doug]

My secret back then, besides a healthy tank was a 250w Iwasaki 65k halide, plus a couple reg actinics. Nothing else. It grew like a weed. I kept it to the main rock it came from and the glass overflows, where it was easily cut for sale or control.

Thx guys to show ur experience. Back glass full of GSP looks amazing but the problems it has seem to weigh more than the pros. I think GSP grows much faster when it encrusted on something.
