While the outside air is introduced into the loading shelf 15 from the exhaust port 61,
The warm air heated by the crab fluorescent lamp 18 is discharged, and the air inside the mounting shelf 15 circulates between the outside of the device 1.

As a result, since the heat of the fluorescent lamp 18 hardly affects the growing chamber 3, the temperature of the growing chamber 3 can be accurately controlled. In addition, since the fluorescent lamp 18 is provided in the mounting shelf 15 installed at an intermediate position in the growing room 3, the flowers and the like placed under the growing room 3 are also satisfactorily irradiated with light. It can be cultivated well.

Further, the spot lamp 1 provided on the top plate 12
1 and the fluorescent lamps 18 provided on the mounting shelf 15 are appropriately switched and controlled according to the growing state of the plants housed in the growing chamber 3. That is, at the time of growing a plant or the like, the control device 39 controls the illuminance by controlling the number of the fluorescent lamps 18 to smoothly grow the plant. In addition, when the cultivation is completed, the illumination can be switched to the illumination by the spot lamp 11 so that the plants last longer and the ornamental effect can be seen (both illuminations 11 and 18 can be turned on). Here, the breeding and the switching of the ornamentation are performed by the user selecting the operation switch 55, and the control device 39 electrically connected to this operation switch causes the control device 39 to grow according to the type of the flower or the plant. Or optimal storage conditions (temperature, humidity,
A program for each plant that produces light, nutrient solution) is set in the microcomputer, and the user is only required to select the operation switch 55 of the plant to be stored.

For example, in the case of Amaryllis, the inside of the growing chamber 3 is controlled to 20 ° C. during the day and to 15 ° C. at night. Is programmed to control at 25 ° C. and at 15 ° C. at night, and the user only needs to operate the operation switch 55 to select the program corresponding to the storage plant.

In the plant growing apparatus thus constructed, the heat of the fluorescent lamp 18 is discharged from the mounting shelf 15 to the outside of the apparatus 1, so that the heat of the fluorescent lamp 18 affects the growing chamber 3. Is almost eliminated, and the temperature of the growing chamber 3 can be controlled with high accuracy. In addition, since the fluorescent lamp 18 is provided in the mounting shelf 15 installed at an intermediate position in the growing room 3, the flowers and the like placed under the growing room 3 are also satisfactorily irradiated with light. It can be cultivated well.

Further, since the cooling unit 4 uses a unit using a metal hydrogen compound without a drive mechanism, almost no noise is generated during operation. As a result, it is possible to provide a plant growing device which does not have a harmful effect due to noise even if the plant growing device is installed indoors and which can always observe the growing state of the housed plant. Further, since the condensed water adhering to the cooling unit 4 using the metal hydrogen compound is supplied into the vase 13 of the flower, water close to pure water can be supplied to the plant, and the flower can last a long time.

Further, it is possible to supply only the nutrient solution which is insufficient in the mounting shelf 16 from the tank 5 into the bowl 14 at any time,
Even when the nutrient solution in the placing shelf 16 is evaporated and the water level is lowered, the nutrient solution is automatically replenished by this amount, and a proper amount of nutrients can always be given to the plant to favorably grow it.

Further, an appropriate amount of nutrient solution for the plants in the pot 14 can be sucked from the placing shelf 16 by the capillary action of the non-woven fabric 51 and stored in the rock wool 49 as a medium. Even if the nutrient solution evaporates and the water level drops, it does not affect the growth of bulbs and seeds. As a result, nutrients can be supplied without wetting the flowers and foliage, the amount of nutrient solution can be saved, and the oxygen permeability of the roots is favorably provided by the air permeability of the rockwool 49, resulting in good root growth. Become.

On the other hand, the nutrient solution in the placing shelf 16 is stored in the growing chamber 3.
Since it evaporates inside, the inside of the chamber 3 is always maintained in a high humidity state.
