I have to disagree. From a commercial perspective such effort would only make sense if it were a species. Granted, within a F3 or F4 you’d be finding plants that would look like the real thing, but since it would technically remain a hybrid for ever and ever… prices as well as chances to sell it for a price that would reflect the effort are slim at best. And having said all this: bench-space is another consideration (and we all know stonei dimensions not even considering the amount of time that would be needed for such a project…)
I love hybrids, don’t get me wrong here, but I know loads of folks who would not look at these plants because they’re not a species, though ultimately I’d expect them to look like the real thing.
