Recently, with the spread of household sprout growers, it is possible to grow and edible sprouts directly at home.

Sprouts grown in these sprout growers do not use pesticides or harmful substances to the human body, and are harvested as health foods because they can be immediately eaten fresh after harvesting.

By the way, the conventional sprout grower is composed of a single cultivation tank, but the cultivation amount is extremely limited, and the cultivation tank is made of a light-transmitting material has a limit that can not create a suitable growth environment for the growth stage of the sprout.

That is, in general, sprouts require light blocking conditions during germination, and light growth conditions are required for growth after germination.

Therefore, the germination rate of the seed is lowered, and the growth of the sprout is not made properly, there is a problem that can not obtain a good sprout vegetable.

In order to solve this problem, the casing is provided with a stepped portion to enable stacking in multiple stages, and is installed to be spaced apart from the bottom surface of the case member by a predetermined height in the case member and the case member of the light-shielding material having a drainage structure formed at the bottom thereof.
