I hope someone can tell me how often I should water an indoor
Hibiscus. It's set by a window that gets indirect light and the room
rarely gets above about 72 degrees. I'm in New England, would it be ok
to put it outside until early Fall?

Sounds like you have a tropical hibiscus. Water as needed -- if it's
leafy and it's in a room with low humidity, those leaves will suck the
soil dry. Tropical hibiscus like water, but they don't want to sit in
soggy soil.

Yes, you can can put it outside, but bring it in before freezing
weather threatened.
