23) with the suction side pipe (18) and the discharge side pipe (
11), each valve (28) (29
) (31) and a temperature 2m 1-section pipe (30) are arranged in the discharge side pipe (11) in the same manner as in the above embodiment, and the boiler (23) is connected to the discharge side pipe (11). The hydroponic solution (11) is heated by a boiler (23). Also, a cooler is installed in place of the boiler (23),
It is also possible to cool the hydroponic liquid in the discharge side pipe (11). In addition, the boiler (23) shown in Fig. 1 has a suction side pipe (1
3), the pressure of the hydroponic liquid acting on the boiler (23) is small, so a small and simple one, for example, one with a structure that can be used as a bathtub in an ordinary household, is sufficient, and a large and pressure-resistant one can be used. When the boiler (23) can be used, it can be connected to the suction side pipe (13) as shown in FIG.
