get to the roots. If they could invent a non-toxic medium then the plant
would surely grow as well as it would in soil. During most
investigations they found that the roots did not respond too well to the
mediums, but that the plant was receiving nutrition in every aspect
when the nutrients were added to the artificial medium by hand. To
solve this problem the inventors looked back into the history of
growing. They found that many Ancient Civilizations where growing
their plants directly in running streams. A light reed or bush was used
to keep the plants stems above the rushing water. Of course the
inventors knew that only certain types of plants could be grown this
way. Then someone had the bright idea of creating a small unit that
held water and had the medium and plant set-up in such away that the
medium would support the plant above the tank that would feed water
to the roots once they grew out from the medium.
