Abstract: A hydroponic growth system comprises grow tubes and a misting assembly. Each of the grow tubes, of a generally hollow cylindrical configuration, are mounted vertically on a support assembly and comprise openings configured on an outer surface of the grow tube for receiving receptacles containing plants. Each of the grow tubes comprise a top vent and a bottom vent. The misting assembly comprises spray tubes inserted into a middle section of the grow tubes to distribute and spray a nutrient solution into an inner surface of each of the grow tubes. The nutrient solution is absorbed by roots of the one or more plants extending into the inner surface of the grow tubes. Unused nutrient solution is drained into a sump positioned beneath the grow tubes via the bottom vents and recirculated within the misting assembly for spraying the nutrient solution to grow the plants.
