Concept design 3 sketches and description 

This system consists of one 4-inch PVC grow tower holding twenty grow pockets along with a reservoir, irrigation system, water and air pump, outlet valve, drainage cover and end cap. The grow tower is 36 inches in length consisting with evenly distributed pockets, 6inches apart with a diametral hole of two inches. This distance gives the plant enough space to obtain maximum leaf coverage. The reservoir chosen is seal tight rectangular container with a length of 15 inches and width 10 inches that is dark in colorations to avoid algae growth. The reservoir stores the nutrient water along with a water and air pump installation. To accommodate the electrical cords, a rubber sealed hole was designed for cord lines to exit the system safely. In addition, an outlet valve was implemented at the base of the reservoir as a drainage mechanism of nutrient water, for sanitation purposes. An irrigation line of 2-inch PVC pipe is connected to the water pump which runs vertically through the center of the grow tower. Due to the height of the system, connectors must be implemented to stabilize the grow tower, thus a female and male adaptor is interlocked onto the reservoir cover with drilled hole size for the tower. At the top of the system, a 4-inch female adaptor is added followed by a 4-inch PVC pipe and end cap. Before closing the system with the end cap, a drainage cover with a center hole half inch was lowered into the grow tower through the irrigation line where it was snug tight due to treading in the female adapter. Thus, system pumps nutrient water through the irrigation line, the end cap reflects the water, falling onto a drainage cover which distributes the nutrient water through the system. Any excess water falls back into the reservoir. The diagram blow shows a sketch of the intended design.
