Section 179 expense - greenhouse

[lionheart]

I've read that a greenhouse could qualify for a section 179 expense if used for a single purpose for business (micro-farming in the suburbs). If we buy a custom greenhouse kit, would this still qualify as section 179? Also, if we got invoiced separately for a contractor to connect the greenhouse kit to our home (we would not section 179 expense this separate invoice), could we still claim the section 179 expense? Thanks!
