FIELD OF TECHNOLOGY
This disclosure relates generally, in one example embodiment, to an automatic hydroponic cloning apparatus, more particularly an automatic hydroponic cloning apparatus to provide a thin mist for watering the roots of plants, to allow for circulation of mist to provide humidity to the leaves of the plants, to control water temperature, to control humidity levels, to be notified of low water levels, and to measure PH levels of the water.
BACKGROUND
Cloning is a form of plant propagation that has been around for a very long time. It's basically taking a growing portion of a plant—a stem with some leaves attached, and helping it to become a brand new plant that is genetically identical to the plant from which the clone was taken. This is often easy to do because plants often clone themselves in nature. It's called asexual reproduction. The methods currently used today include taking cuttings, layering, division, grafting, budding, and tissue culture. Gardeners often trade cuttings and divisions as a way of sharing plants with their friends.
Experiments show that by starting the feeding immediately after the first roots emerge, immunization and seedling strength are increased and young plants experience minimal shock. In addition, experiments show that providing the growing chamber with a mixture of oxygen and solution under slight pressure, and at any selected temperature assists in proper growth of the cloned plants. By misting roots and cuttings, instead of spraying or irrigating, the water is broken down to a nearly molecular level, thereby carrying more oxygen with the solution to the cutting and making absorption easier and minimizing the risk of mold or rotting.
Despite the number of home and commercial growers available, there is still a need for an apparatus for use by the home owner or small commercial concern which is fully automatic until harvest with no human touch. In addition, the prior art teaches that water with some air circulation provides the best combination for cloning. However, new research indicates that maximizing the air with a minimum amount of water makes for better clones with minimal risk of contamination by molds and the like. Further, some commercial units employ misting systems which generally involve forcing water through small pores. However, such misting systems do not mix air with the water but use water pressure to create mist via a nozzle system which does not introduce clean air from outside the growing compartment. This air that is trapped within the growing compartment can be contaminated with bacteria and recirculation increases the chances of contamination. Thus, there is a need to provide a cloning system which does not employ irrigating or misting with pores systems. Furthermore, there is a need for a cloning system which can allow for control and monitoring of humidity levels, water temperature, water levels, and acidity levels which further contributes to the stabilization of the cloning process. This present invention meets those needs.
SUMMARY
Disclosed is, in one example embodiment, an automatic hydroponic cloning apparatus, more particularly an automatic hydroponic cloning apparatus to provide a thin mist for watering the roots of plants, to allow for circulation of mist to provide humidity to the leaves of the plants, to control water temperature, to control humidity levels, to be notified of low water levels, and to measure PH levels of the water.
In one embodiment, an automatic hydroponic cloning apparatus may comprise of a housing having a plant section, a water section, and an exterior control panel.

DETAILED DESCRIPTION
Disclosed are a method, an apparatus, and/or a system of an automatic hydroponic cloning apparatus to provide a thin mist for watering the roots of plants, to allow for circulation of mist to provide humidity to the leaves of the plants, to control water temperature, to control humidity levels, to be notified of low water levels, and to measure pH levels of the water, according to one embodiment.
Reference is now made to FIG. 1, which is a side perspective view of an automatic hydroponic cloning apparatus 100, according to one embodiment. The automatic hydroponic cloning apparatus 100 may comprise of a mist generator 102, a plant section 104, a water section 106, a divider 108, and a control panel 110. The plant section 104 may be encompassed by a transparent cover 112, which may further comprise a plurality of exhaust holes 114 in the rear of the transparent cover 112. The divider 108 may comprise a plurality of net pockets 116, and a plurality of deflector ports 118 positioned in the front of the divider 108. The water section 106 may comprise of a floor 120, a water cup 122, a water pump 124, a heating pad 126, a water level sensor 128, and a pH reader 130.
According to one embodiment, the automatic hydroponic cloning apparatus 100 may be a housing comprising a plant section 104 and a water section 106, which may be horizontally separated by a divider 108. The plant section 104 may comprise of the space between the divider 108 and the transparent cover 112. The water section 106 may comprise of the space between the divider 108 and the floor 120 of the water section 106. The divider 108 may comprise of a plurality of net pockets 116 which may allow for a plurality of plants to rest therein, such that the leaves of the plants are housed in the plant section 104, and the roots of the plants hang above the water section 106.
According to one embodiment, hanging from the rear of the divider 108 into the water section 106 may be a mist generator 102. The mist generator 102 may draw water from the water section 106 and air from outside the automatic hydroponic cloning apparatus 100 and combine them into a mist to be propelled throughout the water section 106 thereby watering the roots of the plants. The description of the mist generator 102 is incorporated by reference from Parent application Ser. No. 11/490,919 and in particular line 12, page 5-line 2, page 7 and FIGS. 3-6.
The water section 106 may further comprise of a floor 120, a water cup 122, a water pump 124, a heating pad 126, a water level sensor 128, and a pH reader 130, according to one embodiment. The mist generator 102, heating pad 126, water level sensor 128, and pH reader 130 may all be communicatively coupled (e.g. electronically connected) to the exterior control panel 110.
According to one embodiment, water may be stored on the floor 120 of the water section 106 and in the water cup 122. The water pump 124 may pump water from the floor 120 of the water section 106 into the water cup 122 when water levels are low in the water cup 122. In an alternate embodiment, the water pump 124 continuously pumps water from the floor 120 of the water section 106 into the water cup 122 such that water levels in the water cup 122 are consistent. The mist generator 102 may then draw water from the water cup 122, according to one embodiment.
According to one embodiment, embedded in the floor 120 of the water section 106 may be the heating pad 126. The heating pad 126 may be in direct contact with the water stored on the floor 120 of the water section 106. The heating pad 126 may increase or decrease in temperature, thereby increasing or decreasing the temperature of the water stored in the water section 106. The temperature of the heating pad 126 may be controlled via the exterior control panel 110. The heating pad 126 may also comprise of a heat sensor which may recognize when the water in the water section 106 has risen above or fallen below the set temperature of the heating pad 126 (the temperature being set through the exterior control panel 110), and may automatically increase or decrease the temperature of the heating pad 126 such that the water temperature resets back to the set temperature, according to one embodiment.
According to one embodiment, the water level sensor 128 may be positioned near the front of the water section 106. The water level sensor 128 may detect when water levels are below a desired threshold, and subsequently transmit a notification to the exterior control panel 110. The threshold may be determined by the physical vertical position of the water level sensor 128. In an alternate embodiment, the threshold may be determined by a point on the water level sensor 128 itself, such that when the water level falls below that point, a notification is transmitted to the exterior control panel 110.
According to one embodiment, the pH reader 130 may be positioned in a front corner of the housing of the automatic hydroponic cloning apparatus 100, and may comprise of a conical or cylindrical shaft that extends into the water section 106 such that it is in direct contact with the water stored in the water section 106, and a display that extends into the exterior control panel 110 where the display can show the current pH levels in the water section 106.
Reference is now made to FIG. 2 which is a close-up cross sectional interior view of the water level sensor 128, according to one embodiment.
Reference is now made to FIG. 3 which is a close up and magnified view of the deflector ports 118, according to one embodiment. The deflector ports 118 may be a plurality of small holes positioned along the front edge of the divider 108. Mist generated by the mist generator 102 may be propelled by the mist generator 102 throughout the water section 106. The mist may then escape the water section 106 through the deflector ports 118 and into the plant section 104, thereby humidifying the leaves of the plants. The remaining mist may then escape through a plurality of exhaust holes 114 positioned in the rear of the transparent cover 112.
Reference is now made to FIG. 4 which is a close-up front view of the control panel 110, according to one embodiment. The control panel 110 may be communicatively coupled (e.g. electronically connected) to the mist generator 102, the water pump 124, the heating pad 126, the water level sensor 128, and the pH reader 130. The control panel 110 may have displays which show current pH levels as detected by the pH reader 130, a notification if water levels are below a desired threshold as detected by the water level sensor 128, and/or the current humidity levels inside the housing. The control panel 110 may additionally have controls for increasing or decreasing the temperature of the heating pad 126, thereby increasing or decreasing the temperature of the water stored in the water section 106. Furthermore the control panel 110 may have controls for increasing and/or decreasing the frequency that the mist generator 102 operates, thereby controlling the frequency with which mist is propelled throughout the water section 106. Humidity inside the housing may therefore be controlled through a combination of control over the water temperature through the heating pad 126 and control over the frequency of operation of the mist generator 102, according to one embodiment.
Although the present embodiments have been described with reference to specific example embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit or scope of the various embodiments. Accordingly, the specification and drawings are to be regarded in an illustrative rather than in a restrictive sense.
