Right. I now have the following orchids:

1 small vanda, won't bloom for two years or so
1 ascocenda
2 cambrias
1 dend.
1 phal.
1 large epidendrum
3 small epidendrum keikis, now on their own.

How much light do these need/want? I will be trying to give the
vandaec... vanda-like ones 20k lumen, but what about the rest?

All of them, less the vandas, are blooming right now. Joy.
