Hydroponic Techniques

Hydroponic Techniques

    The two main types of hydroponics are solution culture and medium culture. Solution culture does not use a solid medium for the roots, just the nutrient solution. The three main types of solution cultures are static solution culture, continuous-flow solution culture and aeroponics. The medium culture method has a solid medium for the roots and is named for the type of medium, e.g., sand culture, gravel culture, or rockwool culture.

    There are two main variations for each medium, sub-irrigation and top irrigation. For all techniques, most hydroponic reservoirs are now built of plastic, but other materials have been used including concrete, glass, metal, vegetable solids, and wood. The containers should exclude light to prevent algae growth in the nutrient solution.

    1. Aeroponics
    2. Bubbleponics.
    3. NFT
    4. Deep water culture (DWC)
    5. Ebb and flow  or Flood and drain.
    6. Fogponics.
    7. Passive sub-irrigation.
    8. Rotary hydroponic garden.
    9. Run to waste.
    10. Static solution culture.
