Ever see this (natural overhead lighting alt.)

Skylight

I've e-mailed the company asking for before and after light meter readings. My thinking is that if it provides a significant (not necessarily a huge) amount of light to go with the south and east windows, I can put a standard roof on the GH and insulate the crap out of it. That would make it easier to heat in winter and cool in summer, as I would have only 168 square feet that would not be insulated.

You can insulate the windows with BubbleWrap from any local packing company. Don't buy it from a GH place because they triple or quadruple the price of it. It's the same product.

I had a skylight a lot bigger than that in the last place I lived. They don't allow as much light to enter as you would think. And it always leaked.

I talked with a rep from a nearby town that sells a similar solar tube. Rather than guess how well it does, she is going to bring a tube. I am tearing down a barn and before I finish it, we will install the tube and take before and after light meter readings.

She says that on a sunny day, they can provide ~32,000 lumens or so. Combined with the light from the south and east walls, that should be enough light I would think.

The solar tubes are designed with reflective material that brings in tons of light even on dark cloudy days unlike a traditional skylight. They have some with lenses designed for the indoor gardener. No electricity to grow indoors!
