I've left things made out of untreated pine outside. They turn grey after
a year or so (SE Virginia). Structurally they are still sound (or at least
appear to be), but now I usually paint wood if it's going to be exposed
outdoors. Don't know if it's a good idea or not for a greenhouse (as far
as plant toxicity and envirofriendliness).

I would say, let them turn grey.

Speaking of structural integrity, are you sure that baby is going to hold
up? I'm not sure how comfortable I'd be with nothing under the rafters.
Are the columns made of wood? It's kind of hard to tell, they sort of look
like PVC pipe. Why not make the whole thing out of pipe? It's got to be
easier to take down (if necessary), probably doesn't need painting and not
near as heavy as wood.

The columns are made pf 1.5" pvc pipe, yes. This greenhouse is not for
winter, it is for planting things on April 1 instead of May 1.

Anyway, good luck, it must have taken a lot of effort to get the framing

Actually, it did not...
