What would be my control group in hydroponics vs. soil?

Im doing a science project and i dont konw what would be my control group..... Please help|||It depends on the hypothesis you're testing. If you're assertion is that hydrophonics is x compared to soil, then soil is you're control.





If you're testing both, then you're doing 2 experiments and don't have a control, unless you want to put a bunch of seeds in water solely. which would probably be an invalid control
