Hanging bottle garden

This is Part One.

This is Part two.

I heard about this before and I totally want to give it a try. I am going to start saving my bottles now. I will use my window in the kitchen or the back patio side door with is fully windowed. I would plant herb and I do not know what else. I guess I will do some research on what people actually grow.
