Not sure. I think they are still relatively rare just because they take forever to grow... Speed will improve as more line breeding happens. You can buy a third generation flask from Chuck Acker (I think third generation) today if you want, not even that expensive - while supplies last, you'll have to take that up with him - I already have mine.Do tell do tell.. what are the secrets to unlocking this flower!!
Lots of oyster shell in the mix, and I top dress with more a couple times a year. Other than that, pretty much like I grow besseae, as cool as I can in the summer and constant moisture.
