As alluded above, the automatic precision weather system is controlled by controller circuit 230 to create a specific favorable plant growing condition in each plant growing drawer 121-124. In one exemplary embodiment of the present invention, the automatic precision weather system (APWS) is controlled to set the growing condition in first plant growing drawer 121 to 1 atmospheric pressure, that in second plant growing drawer 122 to 1.2 atmospheric pressure, 1.4 atmospheric pressure in third plant growing drawer 123, and 0.9 atmospheric pressure in fourth plant growing drawer 124. In another exemplary embodiment, the automatic precision weather system (APWS) in each plant growing drawers 121-124 can be set and observed from touch screen display 130.

[0049] Referring now to FIG. 9, a flow chart of a method for home gardening 900 of different types of plants simultaneously.

[0050] At step 901, a closed enclosure having a plurality of plant growing drawers, each with a vertical lift door and configured to grow a specific type of plant is provided. The close enclosure of step 901 can be implemented with a smart cabinet 100 as described in FIG. 1-FIG. 7(B) above. In many aspects of the present invention, smart cabinet 100 used to implement step 901 has vertical lift door 310 that opens and closes almost parallel to the outer front surface of smart cabinet 100 by virtue of a pair of upward curved hinges 315 and pneumatic arms 316.

[0051] At step 902, an automatic precision weather system (APWS) is provided for each plant growing drawer. In one exemplary embodiment of the present invention, the automatic precision weather system (APWS) of step 902 is implemented which includes an air circulation system as described in FIG. 5, a water circulation system as described in FIG. 6, FIG. 7(A), and FIG. 7(B), a LED lighting systems 811-814, mixing tank 240, and first to fourth water-nutrient solution mixture containers 601-604. In many aspects of the present invention, the automatic precision weather system (APWS) is implemented to provide a specific growing condition for each plant growing cabinet 121-124 so that a specific type of plants/vegetables can grow therein.

[0052] At step 903, each automatic precision weather system (APWS) is programmed to provide a specific growing condition in each plant growing drawer. Step 903 is realized by controller circuit 230 configured to mix the correct specific water-nutrient solution mixture for each water-nutrient solution mixture containers 601-604. Then each distribution pump/valve 611-612 is controlled to pump the correct water-nutrient solution mixture to the correct plant growing drawers 121-124. In there, sprinkler headers 421 mist the roots of the plants/vegetables with the correct water-nutrient solution mixture. Controller circuit 230 also chooses the correct fan speed for fans 521-551 in first plant growing drawer 121, fans 522-552 in second plant growing drawer 122, fans 523-553 in third plant growing drawer 123, and fans 524-554 in fourth plant growing drawer 124. The correct LED light is also chosen by controller circuit 230. It is noted that the light can be chosen by controller circuit 230 ranges from, but not limited to, 380 nm to 800 nm. Any light wavelength suitable to any purposes for growing healthy specific plants/vegetables are within the scope of the present invention. Any excess water nutrient solution mixture in water trays 751-754 is controlled to return to the correct water-nutrient solution mixture containers 601-604 so that water will not be wasted. In another aspect of step 903 of the present invention, the automatic precision weather system (APWS) can be controlled manually by touchscreen 131.

[0053] Continuing with step 903, in various aspects of the present invention, step 903 further includes steps of selecting specific plant to grow in each of plurality of plant growing drawers 121-124; filling water to a proper level in mixing tank 240; pouring a nutrient solution from first solution tank 210 and second solution tank 220 into the mixing tank 240 until the specific water nutrient solution mixture is reached; pumping the specific water-nutrient solution mixture to one of the plurality of water-nutrient solution mixture containers 601-604; repeating the above steps until all chambers of the plurality of water-nutrient solution mixture containers 601-604 are filled with different specific water-nutrient solution mixtures for different specific plants; and controlling the automatic precision weather system (APWS) to provide said specific growing condition to specific plant in each of plurality of plant growing drawers 121-124.

[0054] Step 903 can be implemented by a computer-implemented software program stored in a non-transitory memory device of controller circuit 230. It will be noted that processes 200-900 are performed by a computer software program 190 that is stored in a non-transitory computer readable medium of network server device 140. The non-transitory computer readable medium includes optical memory such as CD, DVD, HD-DVD, Blue-Ray Discs, etc.; semiconductor memory such as RAM, EPROM, EEPROM, etc.; and/or magnetic memory such as hard-disk drive, floppy-disk drive, tape drive, MRAM, etc. The computer software program also includes instructions that display a graphic user interface (GUI) on the display screen of touch screen display 131 and/or any combination thereof. When the GUI is activated by a user, step 903 is performed and the automatic precision weather system (APWS) is set as described above to achieve specific growing conditions for specific plants/vegetables.

[0055] Finally, at step 904, with specific growing condition for each plant growing drawer is established, specific plants/vegetables are grown and cultivated in each plant growing drawer. Step 904 is implemented by growing the following four groups of plants/vegetables:

[0056] Group I: a nutrient ratio of 40 Part per million (PPM) and a pH level of 6.0 to 7.0 in first plant growing drawer 121; example of group I includes water cress.

[0057] Group II: a nutrient ratio of 540-1,000 Part per million (PPM) and a pH level of 6.0 to 7.0 in a second plant growing drawer 122; example of group II includes artichokes, lettuce, asparagus, corianders, and cinnamon.

[0058] Group III: a nutrient ratio of 1,200-1,600 Part per million (PPM) and a pH level of 6.0 to 6.5 in third plant growing drawer 123; example of group III includes beans, bell peppers, carrots, cauliflowers, mints, basils, and cucumbers.

[0059] Group IV: a nutrient ratio of 1,700-2,100 Part per million (PPM) and a pH level of 5.5 to 6.5 in fourth plant growing drawer 124; example of group IV includes tomatoes and cabbages.
