PURPOSE:To obtain the subject apparatus for water culture capable of simply assembling and controlling the inclination of a fruit vegetable bed to a desired angle by changing the number of piled lower bases by making the constitution capable of engaging the fruit vegetable bed with the upper part of a lower base through an upper base. CONSTITUTION:Respective terminal box members 11 and 12 made of an expanded plastics are placed opposite a middle box member 13 and connected thereto to form a fruit vegetable bed 10. An upper base 20 made of an expanded plastics and having the upper surface capable of mechanically engaging with the under surfaces of the terminal box members 11 and 12 and of the middle box member 13 is provided under the connection part of the terminal box units 11 and 12 and of the middle box member 13. A lower base 30 made of an expanded plastics and having the upper surface capable of mechanically engaging with the under surface of the upper base 20 is also provided. Plural number of the lower bases 30 are piled up in accordance with the angle of inclination of the fruit vegetable bed 10, and the upper base 20 and the fruit vegetable bed 10 are subsequently engaged with the upper part thereof in order, thus assembling the objective apparatus for water culture. |
