Hydroculture

Type: Concept
Description: Hydroculture is a method of growing plants without soil, using mineral nutrient solutions in an aqueous solvent.

Attributes:

• Nutrient Solution: The solution provides essential minerals and nutrients required for plant growth.
• Water Usage: Typically uses less water compared to traditional soil-based gardening.
• Plant Types: Suitable for a wide range of plants, including vegetables, herbs, and ornamental plants.

Relationships:

• Related Entity: Hydroponics
  Relationship Type: Is a subset of
  Description: Hydroculture encompasses various methods, including hydroponics, which specifically refers to the use of nutrient solutions without soil.

• Related Entity: Aquaculture
  Relationship Type: Is associated with
  Description: Both practices involve water-based cultivation, though aquaculture focuses on the farming of aquatic organisms.

From Wikipedia:

Passive sub-irrigation, also known as passive hydroponics, semi-hydroponics, or hydroculture,^[52] 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 simplest method, the pot sits in a shallow solution of fertilizer and water or on a capillary mat saturated with nutrient solution. The various hydroponic media available, such as expanded clay and coconut husk, contain more air space than more traditional potting mixes, delivering increased oxygen to the roots, which is important in epiphytic plants such as orchids and bromeliads, whose roots are exposed to the air in nature. Additional advantages of passive hydroponics are the reduction of root rot.
