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 ...
