Grow Ball

This is the Grow Ball. We ordered it online but i can't remember where from. It is a soiless hydroponices sytem that works kind of like Chris' self-watering containers. The top is filled with a perlite/coco mix (the white and brown stuff) and the bottom is filled with water and nutrient solution. Right now i am trying a Patio tomato plant in it under a standard compact flourescent light. I plan to move it outside once it gets warm enough because it won't flower under this light.
