However, this space may be filled with another material, such as a coarser felt or a coarser, more porous sponge, which does not retain water but is effective as a support base for roots. In addition, shade the root part to make it dark.
  • the roots grow in the direction of gravity, that is, downwards, with sufficient nutrients, moisture, and darkness.
  • it can grow freely in the horizontal direction, it spreads horizontally and becomes a large root, which absorbs a large amount of nutrients and water and increases the production of edible leaves and fruits.
  • the felt would sag, and to prevent this, the felt would have to be stiff, and the softness and sparseness of the felt would not be maintained.
  • step 3 After the process of step 3 was completed, holes with a diameter of 10 cm and a depth of 1 cm were formed on the surface of the dry hydroponic cultivation unit 60 at 50 cm intervals on the felt of 2 m x 2 m and 20 cm in thickness. become.
  • This hole (through hole 69) with a diameter of 10 cm and a depth of 1 cm serves as a seedbed, and the leaking portion 71 of the irrigation tube portion 68 is positioned at the center thereof, so that the irrigation liquid leaking out from the leaking portion 71 promotes the growth of plants. prompt.

By doing so, the plant is manufactured in an environment that is as close to aseptic as possible, which has the advantage of preventing bacteria and mold from adhering and reducing the damage caused by bacteria and mold during the growth process.
