Description

Absorption medium for hydroponics and cultivation apparatus using the same {ABSORPTION MEDIUM FOR HYDROPONICS AND CULTIVATION APPARATUS USING THE SAME}

Embodiments of the present invention relate to a cultivation technique using an absorbent medium for hydroponics.

In general, hydroponics is a scientific farming technique that allows various crops to be cultivated by supplying a culture medium containing all the nutrients necessary for plant growth by an appropriate nutrient solution supply method. Cultivation that can overcome various problems occurring in soil cultivation method. There is a solid medium cultivation method using a medium for such hydroponics, and rock wool, perlite, peat moss, urethane foam, etc. are used individually as solid medium.

However, the solid medium of this configuration has a small amount of water retention, so the supply cycle of the nutrient solution needs to be shortened, so the consumption of the nutrient solution is high, and there is a problem that the lower part of the medium is over-moistened to inhibit the growth of plants.
