Messing with nature, I think they suck.
To the OP, the hybrids you see here and in the above posted thread, have all come from breeders here in Japan and a few in Indonesia.
These breeders (few big name ones) have been trying this for years and years. I mean decades...
Other than the "easy Ansorgii x Endlicheri" mix, these breeders have seen very limited success!
So by all means try, but IMO it isnt worth wasting your time and money.
