Since i've got some 3/4 hardwood which I can't use upstairs,

Is the issue with hardwood below grade strictly an issue of moisture
and subflooring?



Sorry, it is not recommended unless you take special steps, like putting
insulation and vapor barrier between 2 x 4 sleepers. You lose a lot of
headroom that way and a PITA in places. You can use engineered hardwood
though, along with the proper barrier.
