I do strongly recommend against watering with window cleaner.
To this day I don't know what I was thinking when I did that
(Hadn't had my morning caffeine yet). Didn't kill the dendrobium,
but did stop a new shoot from growing any more.

Not to giggle at your mistake, but LOL! A couple of weeks ago I grabbed for
liquid tears and blindly picked up a bottle of liquid nail hardener. Whoa,
did that burn!
