[Problems to be solved by the invention]
The conventional hydroponics bed has the following problems because the distance between the bed main body and the lid placed thereon is constant.
1. When the plant is small, the number of roots is small and the length is short, but when the plant grows and becomes large, the number of roots increases and the length also increases. For this reason, when the number of roots is small and the length is short, if the interval is too wide, the roots are difficult to touch the liquid flowing in the bed, and the absorption of the liquid becomes insufficient, which adversely affects the growth of the plant. There is a fear. On the other hand, if the number of roots is large and the length is long and the interval is narrow, the roots grow densely in the bed and become difficult to grow, or become deficient and adversely affect plant growth. Sometimes.
2. In order to solve the above-mentioned problem, when the number of roots is small and the length is short, plants are planted in the hydroponic bed with a narrow interval, the number of roots is increased, and the length is increased, It is only necessary to replant plants in the hydroponic bed with a wide interval, but doing so makes the work of replanting difficult, and for that purpose, two types of hydroponic beds with different intervals must be prepared. In addition, the equipment cost is high and the transfer work is troublesome.
