Why Howdy!! I just stumbled onto your site, so please forgive a dumb question. I saw some pic.s and there seems to be dirt in the gallon jugs, I was under the inpression that "hydroponics" was just water? What else can you use instead of dirt? How do you keep the dirt from mixing with the water and cloging the
pump? Thats all for now,
