I love it.......a few days ago he woke up and decided he needed an orchid,
and already we're talking about a mini greenhouse.

1: Take Wendy's excellent advice and provide your baby with what it would
get in its natural habitat.
2: Yes, a fishtank would work.
3: Your plant will need decent air circulation, so you don't want to
completely wrap it up in plastic. In larger GHs there are big fans to keep
the air moving.
4: Forget the 'one orchid' idea. It doesn't work that way! They multiply
when you least expect it. (Well, okay, it's like potato chips. Nobody can
have just one.......)
