The great thing about hydroponics is how flexible it really is. Hydroponics can easily be combined with aquaculture to make aquaponics. Aquaponics provides a more-or-less closed nutrient cycle between the hydroponics, which requires additional nutrients, and aquaculture, which requires filtering the excess nutrients out of the water.
This is especially relevant in the design, architecture and construction of an underwater or subterranean habitat. To produce the maximum amount of food per cubic foot of space, growing both fish and other aquatic livestock with food crops is essential.
One of the best aquaponics fish is tilapia, which produces a lot of food per fish, grows quickly, and is easy to breed from broodstock. Other options include oysters, crab, crayfish, prawns and lobsters.
For the plants, strawberries and blackberries top my list. Oats, barley, rice, beans and peppers are all favorites of mine. Although growing them in this neon environment may be tricky, coffee, tea and other money crops, such as sugarcane and cotton, are all valuable crops and may be able to offset some of the expense.
All plant life, including the crops, need carbon dioxide, but at such hyperbaric pressures, that of enabling moon pools in ocean depths of 4,000 to 6,000 meters (~13,000 to ~20,000 feet) below sea level, carbon dioxide is poisonous to humans, even at low partial pressures. For this reason, cryogenic liquifaction and fractional distillation of neon-oxygen breathing gas to extract the carbon dioxide exhaled by humans and livestock, including aquatic livestock such as fish and crayfish, and deliver that gas in liquified form, to sealed robot-farmed modules. These modules contain a much larger partial pressure of carbon dioxide, which is extracted and pumped from the exterior tunnel system.
This allows the plants to have plenty of carbon dioxide, while still having plenty of oxygen dissolved in the water to permit the plant to breathe. As an additional measure to reprocess the carbon dioxide, aquatic plants such as water hyacinths and watercrest can be cultivated to take up shallow wastewater troughs to help treat the water and consume the carbon dioxide. There are some NASA experiments regarding hyperbaric hydroponics that indicate that many crops grow exceptionally well under hyperbaric growing conditions.
