Solution

Hydroponic technology:

  1. Hydroponics is a soil-less culture of plants.
  2. In hydroponics, plants are made to grow by immersing their roots in a aqueous solution which contains minerals.
  3. They can also be rooted in a medium containing sand which is moistened by an aqueous solution.
  4. In a hydroponic technique, the plant is supported in a peat bed or wire screen with roots dipped in an aqueous mineral solution.
  5. Aeration for the solution has been provided.
  6. Another method is to root the plants in a medium of gravel or sand present within a shallow tank into which the aqueous solution is pumped automatically at intervals.
  7. Between the pumpings, the solution gets drained into a reservoir tank.
  8. Hydroponics is an outdoor technique practiced in green houses.
