You probably can defeat any moisture problems at the shop side, but
you may not be able to easily defeat any moisture problems if there's
an entry or other opening into the greenhouse from the shop. The
greenhouse moisture, though, will quickly rot T1-11, so you need some
other surface on that area. You might be OK with housewrap alone on
the side of the shop, or a good coat of enamel on the plywood might do
the job.

...depending upon what you intend to grow in there, how water is
applied and
what kind of venting you intend to have.

If your green house is for cacti (I've been in a few) I'd expect no
problems.
Even an orchid house might be o.k. if you water discreetly and ensure
that
the plants dry thoroughly between waterings (a must). Sealed, un-
watered
T1-11 will likely endure this exposure for many years. Probably
easier on
siding than Seattle weather.
