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

I would buy plants that will fit in the solo cups and wash the dirt off . Buy a few more to keep in dirt to compare with. If you can get the solution right then it won't take long to see the difference.
