Hydroponic carrots, potatoes..?

Question:can potatoes, and carrots be grown with hydroponics?
because the fruit of the plant would be mirking in the nutrient fluid... does anyone know??

Answers:
I don't know about potatoes, but I have seen carrots growing.When you think of it George, you only need the roots in the medium.If you suspended a bag with a potato plant in it and let the roots down in the medium it would ok.It actually makes me realise it could be a good way to grow them. But personally i like to grow things a little more exotic, potatos and carrots are cheap enough to buy.
