Here's teh interior taken down the length of the GH, standing in the
doorway. The floor is brick, the benches are eggcrate light diffusers in
the original GH (in the back) and in the (front) addition you can see I
didn't go so fancy, I went with plain old shelves from Home Depot.

The second shot is looking back toward the door, I used that metal support
one uses to strenghten concrete to hang plants. The grid allows for a
myriad of positions.
