The size and number of through-holes (3) may be determined as appropriate.When cultivating non-bulky plants such as green onions, many through-holes are provided. It is advisable to reduce the number of holes. In this embodiment, a large diameter through hole and a small diameter through hole are provided so that one apparatus can be applied to cultivation of different types of plants. Therefore, plants with thick and large stems should be attached to large through holes, and plants with thin and small stems should be attached to small through holes. Further, the through-hole (3) at any position may be used according to the size of the plant, and the unused through-hole (3) may be closed with a sponge or the like.

If the lid (2) has a sufficient thickness, the through-hole (3) may be formed simply by providing holes penetrating the lid (2) on the front and back sides. If the thickness of the through hole is small, it is difficult to hold the plant with a holding material such as a sponge described later.Therefore, it is necessary to increase the axial length of the through hole by attaching a separate cylindrical member. desirable. In the present example, a through hole (3) having a cylindrical portion (3a) around it was formed integrally with the lid (2).
