Hydroculture is a form of passive hydroponics and a way of growing plants without soil. Passive hydroponics systems often use an inert growing medium such as clay pebbles instead of soil. If you haven't experimented with hydroponics before, then passive hydroponics and hydroculture is a great way to get started

Hydroculture system is often made up of five simple parts:

• liners/ outer pot (for holding the water reservoir)
• culture pot (inner growing pot)
• growing medium (expanded, fired clay pellets)
• water level indicator
• nutrient (fertilizer)

Pot liners

Pot liners are often used in hydroculture and other forms of gardening to make easy work of moving plants between containers. Pots used for display purposes, waterproof and encourage the development of a smaller, more manageable root zone in plants placed in large outer containers.

 

Culture pots

The culture pot is the heart of the hydro system, available on the market in many different sizes to accommodate an assortment of plants. Fitting snugly into the outer pot, it is made of plastic with slits all around the base that guarantee maximum air flow through the growing medium and the root zone. The design of the culture pot also allows for a water level indicator to be attached firmly. With its concave bottom, only the external portion of the pot makes contact with the outer pot and the nutrient solution. The special design of the culture pot assures that the plant’s root are not growing in water; they are growing above the water, surrounded by the clay pellets, which draw the moisture up by capillary action from the supply in the outer pot. Roots are never wet, just evenly moist.

 

Water level indicator

The water level indicator (with adjustable memory scale for the next fertilization month), resembling a thermometer, fits neatly into a slot in the culture-pot and is used as a water gauge. There are three markers on the indicator: min (minimum), opt (optimum), max (maximum). The marker in the indicator rises as water is added and falls as the water is used up by the plant. When the indicator reaches the minimum level, it signifies that the pot is completely empty and it’s time to add water. The water level should always be kept at the opt (optimum) level. Only under special circumstances should you fill the pot to the max (maximum) mark, such as extended absences from home.
