Description:
FIELD OF THE INVENTION 
     The present invention relates plant watering system and, more particularly, to a watering system for both indoor and outdoor plant usage. 
     BACKGROUND OF THE INVENTION 
     While outdoor gardens typically have pre-installed water systems capable of water plants in a pre-defined schedule, such as time, water flow rate, etc, indoor gardens especially small patio sized are normally not such equipped due to room limitation. Some indoor plants need re-positioning on a daily basis for proper ventilation, sun shine, especially in cold areas. The plants are moved outside for sunshine in the morning, moved inside to avoid cold weather. Hence, there is a need for a portable plant watering system flexible enough for provide watering needs for both indoor and outdoor applications with minimum laboring work involved. 
     Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims. 
     SUMMARY OF THE INVENTION 
     The present invention features a portable plant watering system. The system comprises a liquid bottle, an attaching means, a liquid bottle connector, a plurality of flexible water tubing, a plurality of T-connectors, a plurality of water outlet ports to water multiple plants. Each water outlet port is integrated with adjustment means to adjust water flow rate individually accordingly. The plant watering system can be set-up on porch or patio effortlessly thus provide a quick solution for in-door garden water needs.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Referring now to  FIG. 1-6 , the present invention features a portable plant watering system ( 100 ). The system comprises a liquid bottle ( 110 ), a liquid bottle connector ( 120 ), a plurality of T-shaped fittings ( 130 ), a plurality of liquid outlets ( 140 ), a plurality of tubing ( 150 ), a plurality of pots ( 148 ) and a plurality of plants ( 146 ) with each plant inside one pot. 
     The liquid bottle ( 110 ) has an opening ( 112 ), wherein a liquid ( 116 ) is filled inside and drained through the opening ( 112 ). In some embodiments, the liquid ( 116 ) is water. In some embodiments, the liquid ( 116 ) is water mixed with liquid fertilizer, solvable plant foods, pesticide, or a combination herein. In some embodiments, the liquid bottle ( 110 ) has a volume scale on side wall so that the user can monitor the total volume of the liquid to be watered into the plants. In some embodiments, the liquid bottle ( 110 ) is a standard 2-liter or a standard 1-gallon water container. 
     The liquid bottle connector ( 120 ) comprises a cap ( 122 ) and a tubing connector ( 124 ). In some embodiments, wherein the opening ( 112 ) of the liquid bottle ( 120 ) is threaded, wherein the cap ( 122 ) of the liquid bottle connector ( 120 ) are threaded, wherein the threads of the opening ( 112 ) and the cap ( 122 ) are matched. In some embodiments, the tubing connector ( 124 ) of the liquid bottle connector ( 120 ) is a barbed connector. 
     The system comprises a plurality of T-shaped fittings ( 130 ), wherein the T-shaped fitting comprises a left arm ( 131 ), a right arm ( 132 ) and a middle arm ( 133 ), wherein the left arm ( 131 ) and right arm ( 132 ) are aligned on the same line, wherein the third arm ( 133 ) is perpendicular to both the first arm ( 131 ) and second arm ( 132 ), wherein the first arm ( 131 ) is in the water flow upstream. The fittings ( 130 ) can be a variety of types, such as push-to-connect fitting, quick connect fitting, compression fitting, barbed fitting etc. The T-shape fittings are well known to one of ordinary art in the field. Preferably, the left arm ( 131 ), right arm ( 132 ) and middle arm ( 133 ) of the T-shaped fitting ( 130 ) are all barbed. 
     The system comprises a plurality of liquid outlets ( 140 ), wherein the water outlet has a top connector ( 141 ), an adjuster ( 142 ) and liquid release port ( 143 ), wherein the adjuster ( 142 ) regulates liquid flow rate, wherein the liquid ( 116 ) is released to irrigate plant ( 146 ) inside a pot ( 148 ). In some embodiments, the top connector ( 141 ) is a barbed connector. In some embodiments, the adjuster ( 142 ) of the liquid outlet ( 140 ) is a valve with a knob disposed outside of the valve ( 143 ), wherein the liquid flow rate is adjusted by adjusting the position of the knob. In some embodiments, the adjuster ( 142 ) of the liquid outlet ( 140 ) is a set of a threaded opening and a threaded cap, herein the liquid flow rate is adjusted by adjusting the tightness of the threaded cap over the threaded opening. Preferably, the valve with knob is used because the user can easily and quickly identify the water flow rate by viewing the adjust knob position. The knob of each liquid outlet ( 140 ) can be adjusted independently for the watering requirement of each specific plant. 
     A first plurality of tubings ( 150 ) are used to fluidly connect the said tubing connector ( 124 ) to the left arm ( 131 ) of the T-shaped fittings, to connect two T-shaped fittings immediately adjacent. A second plurality of tubings ( 155 ) are used to fluidly connect the third arm ( 133 ) of the T-shaped fitting ( 130 ) to the top connector ( 141 ) of the said water outlet. The adjuster ( 142 ) and the liquid release port ( 143 ) are located at a terminus ( 180 ) of the second plurality of tubing ( 155 ). The tubing ( 150 ) is made of polypropylene, Teflon, polyethylene, Polyvinyl chloride (PVC), polycarbonate or rubber. In some embodiments, the tubing ( 150 ) has a diameter ranging from ⅛ inch to 4 inches. The liquid inside the bottle ( 110 ) is flowing out via the opening ( 112 ), passing through the liquid bottle connector ( 120 ), diverted into a plurality of said T-shaped fittings ( 130 ) via a first plurality of tubings ( 150 ), irrigating the said plants ( 146 ) in each pot ( 148 ) via a second plurality of tubing ( 155 ) and liquid outlets ( 140 ). 
     In some embodiments, a cartridge ( 156 ) is disposed inside each of the tubing ( 155 ). The cartridge ( 156 ) is filled with solids ( 157 ) such as pesticide or plant food. The solids are soluble with water. The solids can be the same for all cartridges or alternatively, the solids are different for each cartridge such that each plant get individual irrigation solutions. 
     In some embodiments, the system ( 100 ) further comprises a rod holder ( 160 ) and attachment means ( 170 ) to attach the liquid bottle ( 110 ) to the holder ( 160 ). The attachment means ( 170 ) can be a strap, a rope tie, etc. The rod ( 160 ) can be easily attached to any porch or patio.
