Systems and methods for controlling liquid delivery and distribution to plants

1. A hydroponic system for providing liquid to a plant or a seed that can germinate into a plant, said system comprising:

a) a liquid delivery device;

b) an actuator for controlling delivery of liquid to the plant or seed;

c) an electronic controller circuit board operatively connected to said liquid delivery device and said actuator;

d) a vessel comprising a first component of said actuator; and

e) a vessel support removably attached to said vessel and comprising a second component of said actuator;

wherein said actuator is controlled by said electronic controller circuit board and is electrically operable only when said vessel is brought into contact with said vessel support such that said first component of said actuator contacts said second component of said actuator to form a complete electric circuit; f) a vessel cover; g) a plant or seed located in said vessel, wherein the plant or seed grows through an opening in said vessel cover.

2. The system of claim 1 wherein said liquid delivery device comprises a submersible pump.

3. The system of claim 1 wherein said actuator causes said liquid delivery device to deliver said liquid by providing energy to said liquid delivery device.

4. The system of claim 1 wherein said actuator is a switch.

5. The system of claim 1 , wherein said first component and/or said second component is a characteristic selected from the group consisting of: elastic, springing, reversibly bendable, and bendably biased outwards.

6. The system of claim 1 , said first component comprises gold-plated spring steel.

7. The system of claim 1 , wherein said second component comprises nickel-plated steel.

8. The system of claim 1 wherein said liquid is aqueous and comprises plant nutrients.

9. The system of claim 1 wherein said liquid is not delivered to said plant or seed when said vessel is moved out of proximity with said vessel support.

10. The system of claim 1 , wherein said vessel comprises an electrical contact unit and said vessel support comprises a complementary electrical contact unit such that said actuator is operable only when said electrical contact unit is in contact with said complementary electrical contact unit.

11. A hydroponic method for providing liquid to a plant or a seed that can germinate into a plant, said method comprising: a) providing a system of claim 1 ; b) providing a plant or seed; c) providing a liquid; and d) delivering said liquid to said plant or seed using said system.

12. A hydroponic method for reversibly providing liquid to a plant or a seed that can germinate into a plant, said method comprising:

a) providing an actuable device, said device comprising:

i) a liquid delivery device;

ii) an actuator for controlling delivery of liquid to the plant or seed;

iii) an electronic controller circuit board operatively connected to the liquid delivery device and the actuator;

iv) a vessel comprising a first component of said actuator; and

v) a vessel support comprising a second component of said actuator;

wherein said actuator is controlled by said electronic controller circuit board and is electrically operable by forming a complete electric circuit only when said vessel is brought into contact with said vessel support such that said first component of said actuator contacts said second component of said actuator;

b) providing a plant or seed;

c) providing a liquid; and

d) using said actuable device to deliver said liquid to said plant or seed; wherein said plant or seed located in said vessel grows through an opening in a cover on said vessel.

13. The method of claim 12 further comprising reversibly moving said vessel into proximity with said vessel support.

14. A hydroponic system for providing liquid to a plant or a seed that can germinate into a plant, said system comprising:

a) a liquid delivery device;

b) an actuator for controlling said liquid delivery device;

c) an electronic controller circuit board operatively connected to said liquid delivery device and said actuator, wherein said electronic controller circuit board comprises an on/off switch;

d) a vessel comprising a first partial electrical circuit; and

e) a vessel support comprising a second partial electrical circuit;

wherein said actuator is electrically operable only when said vessel is placed on said vessel support such that said first partial electrical circuit contacts said second partial electrical circuit to form a complete electric circuit of said actuator, thereby allowing said actuator to be controlled by said on/off switch of said electronic controller circuit board; f)a vessel cover; g)a plant or seed located in siad vessel, wherein the plant or seed grows through an opening in said vessel cover.

15. The system of claim 14 further comprising an artificial light source.

16. The system of claim 15 , wherein said actuator is capable of controlling said artificial light source.
