Rhizofiltration may be applicable to the treatment of surface water and groundwater, industrial and residential effluents, downwashes from power lines, storm waters, acid mine drainage, agricultural runoffs, diluted sludges, and radionuclide-contaminated solutions. Plants suitable for rhizofiltration applications can efficiently remove toxic ...
The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are required.

The Lunar greenhouse is an underground farm made by Phil Sadles and Gene Giacomelli of the University of Arizona's Controlled Environment Agriculture Center (CEAC) [4] [5] The urine and exhaled air of the astronauts is reused in the system by the plants. [6] GreenForges is a Canadian startup developing underground farming systems. [7] [8] [9]
Passive sub-irrigation, also known as passive hydroponics, semi-hydroponics, or hydroculture, [51] is a method wherein plants are grown in an inert porous medium that moves water and fertilizer to the roots by capillary action from a separate reservoir as necessary, reducing labor and providing a constant supply of water to the roots. In the ...
Tomatoes grown in this manner produced about double the yield of tomatoes grown alone - or "monocropped" - in the same simulated Martian soil, with more and bigger fruit.
Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.
Edible halophytes that can be grown in hydroponic systems include New Zealand spinach, common ice plant, common glasswort, barley, rice, and swiss chard. Algae, seaweed and plankton may be grown as well, possibly in combination. [2] The relationship between salinity and optimal growth of halotolerant and halophilic plants varies by species ...
The water districts said California’s water operations are “incredibly complex” and that the movement of water supplies “requires an extensive understanding of the plumbing, safety ...
