PURPOSE:To improve growth of a plant by providing a fountain means in a transfer pathway of cultivating solution fed from a cultivating solution tank to a culture trough and a means attracting eyes of appreciators by driving a rotor in the fountain and oxygen is sufficiently mixed into the cultivating solution. CONSTITUTION:A cultivating solution is pumped up by a pump 6, ejected into a room (I), sprinkled while rotating a rotor 8 with wings 8a by jetting force and the flowed cultivating solution is received by a saucer 5. Cultivating solution flowed from a hole 'a' in the bottom of the saucer to a upper trough 9 is overflowed from a weir 10 to a culture trough 2. The cultivating solution flowed from pouring port 12 into a cultivating solution tank 1 is pumped up by a pump 6 and circulated. |
