I live in a condo. That means that all the windows have to be uniform on all the "units." I've always wanted a greenhouse window in my kitchen so that I could enjoy herbs growing right there where I need them. But being that I live in a condo, I can't install one.
On either side of my kitchen sink window, that is, the window that's right in front of my sink, there are these tiny shelves. They're not very useful except for putting cute things on. So a couple of days ago, I went out and bought a piece of wood that has the same depth (or width) as those little shelves, and created my own little makeshift greenhouse window! I just placed the wood on those little shelves for support, and here's the result:
Next step as the herbs grow and need more light is to place another plank of wood at the top shelves, and affix a grow light to the underside so that it'll shine directly on my herb plants!
I guess I could sand and stain the planks too, but right now, I'm enjoying the fragrance of fresh-cut wood as I wash my dishes.
Hope this is useful to someone.
