Any ideas that could help with my hydroponics presentation?

I have to give a powerpoint and props presentation on Deep water culture (DWC) hydroponics in a week and i need some resources and references fast. Also, I'm experienced in growing hydroponically, but only with marijuana. Is there another plant that is similar that I could use as an example like tomatoes or something? (I don't exactly want the whole world knowing I used to grow pot....thank the gods for internet anonymity lol:-)
