Last year I built my first hydroponics garden. I was trying to do it all inside, and in doing so my lighting bill was eating away at my spending cash. This summer I have decided to move the garden outside where there is plenty of sun light. The only problem is I do not have power to run the pump. This is how I am getting around that issue.
Talking with Dell and Aaron, we were thinking how cool it would be to have a room covered with white boards. There is paint that you can put on walls that makes them into a big white board. Then we though what if a person made the walls into rear projection screens that had overlays. What do you think? How would you make it?
