What does hydroponics mean?

With hydroponics, plants can grow without soil, a very new technology. Instead, a water-based treatment gets straight to their roots and gives them the necessary nutrients. Hydroponic systems include the wick system, nutrient film methods (NFT), and deep water culture.

Why hydroponic farming is an excellent idea:

  • Better efficiency: Hydroponic farming requires less water than traditional gardening.
  • Space optimization: it allows urban and vertical farming, which makes the most of small spaces to grow more food.
  • Faster growth: Plants grow faster and produce more when pH and nutrient levels are correct.
  • Less pests: Since there is no soil, pests and diseases are less likely to spread.
