Yes 171 plants; a teenie, tiny collection! oke:
That's paphs only. Add there my phalaenopsis etc. and it will be way over 200.
I converted my smaller "phalaenopsis" tank into "paphiopedilum nursery":
The now enjoy lovely shade from large phals on the middle shelf, 80% humidity and 23-25C temps during the day.
Of course lots of phals had to move out to large tank with average of 18C temps and 60% humidity, but they should be fine, they are grownups.
