Hydroponics system including stacked grow reservoirs with shared drain out system

A method comprising:

• arranging a vertical row of reservoirs, including 1) at least two grow reservoirs vertically stacked on top of one another;
• and 2) a control reservoir stacked beneath the at least two grow reservoirs;
• pumping water from a shared water pump located in the control reservoir into the vertical row in a hydroponics system;
• circulating the water at a constant rate in a closed loop configuration through the vertical row, including moving the water through multiple irrigation tubing, each irrigation tubing connecting the at least two grow reservoirs and a control reservoir to each other;
• transporting air from a shared air pump to the water in the at least two grow reservoirs through aeration tubing;
• draining the water from a first grow reservoir into a second grow reservoir located below the first grow reservoir;
• and
• draining the water from the second grow reservoir into the control reservoir.

A hydroponics system, comprising:

• at least two grow reservoirs for holding nutrient solution arranged vertically stacked on top of one another;
• a control reservoir located beneath the at least two grow reservoirs;
• at least one shared water pump to circulate water via irrigation tubing between the at least two grow reservoirs and the control reservoir in a closed loop configuration throughout the hydroponics system;
• a shared float valve to maintain a predetermined water level;
• a shared air pump to transport air from the shared air pump to the nutrient solution in the grow reservoirs via aeration tubing;
• a shared water chiller configured to lower the temperature of water in the hydroponics system;
• and
• a shared drain out system to drain water from the at least two grow reservoirs and the control reservoir in the hydroponics system, wherein a first grow reservoir drains the water into a second grow reservoir located below the first grow reservoir, and the second grow reservoir drains the water into the control reservoir.
