I got a crazy idea to try to grow in a little stream in some woods. the stream is about 10 feet wide and up to 5 feet deep in places (not that big, I know). The Setup The base is some 2 inch thick Styrofoam that is 2.5' by 1.5'. It has a hole in the middle just big enough to fit the bottom of a 2 liter bottle. Cut a 2 liter just about half way down, and put holes in it. Fill the bottle with fertilizer and insert it into the foam with 2 inches sticking out the bottom. Find a sunny place in the river to put it. Finally put a germinated seed in the dirt and tie it off to a tree. here's a pic. Tell me what you think.
