Have u fellows ever heard of "Solartubes"? They install them from the exterior roof to your ceiling, and of course, it's a tube. It has a round dome on top, low profile and is the tube is reflective. It's an easy way to brighten any room quickly and cheaply, completely passive.
I was thinking a large one might be able to handle a pretty good sized plant. You can seal the ceiling end with a cap so no light comes out and conceals the plant.
Just a rough idea but some you wintering chaps might benefit. Surely if it did work, you would be finishing inside one right now.... rain be danged..... <----uh buggered?
