Once upon a time I had a dream of building a greenhouse off my classroom. The idea was to grow a plethora of plants for butterflies to live with. The plan was to plant them in soil that our classroom worms would produce. Of course, we would raise our own butterflies to release.
That was the plan. This was a book I purchased to help further it.
It was okay. I learned from it. Not surprising, my plan never came to fruition. :(
