hydroponics garden for a science fair project?

[Matt]

ron I am a 7th grader considering doing a hydroponics garden for a science fair project? Do you think this will be to difficult. We feel we could build the 11 plant garden-but we're unclear on what else we need to get started. Should I start the seeds in dirt 1st or buy plants already growing. I want to compare plants growing hydroponic to growing in soil. Thanks Matt
