A microponic irrigation system is formed using a plurality a grow tubes, apressure manifold, and a drainage manifold. Each of the plurality of growtubes definesa grow chamber within the interior of the grow tube and is provided with atleast onecradle assembly to support of a plant disposed with its roots suspended in airwithin thegrow chamber. The pressure manifold fluidly couples a reservoir to each of thepluralityof grow tubes and delivers nutrient solution housed in the reservoir to theplurality ofgrow tubes under pressure. The pressurized nutrient solution delivered to thegrowtubes is misted into each grow chamber to be absorbed into the roots of eachrootedclone supported in the grow tube. The drainage manifold collects unabsorbednutrientsolution from each of the plurality of grow tubes and circulates theunabsorbed nutrientsolution back to the reservoir.
