IMHO:

Injecting any moisture into your crawlspace is a bad idea. See if you
can have a condensate pump setup to pump it into a better area. Maybe
a drain somewhere.

Just guessing....

At the very least, Continue the plastic to cover the whole area
with a tight seal around the pipe, so the moisture doesn't evaporate
into the crawl space.
