Aeroponic system

Abstract

An aeroponic root system comprises a plant cell having a first root chamber coupled to a second root chamber. A perforated divider may be disposed between the first root chamber and the second root chamber. In some examples, a fluid delivery system may convey water, nutrients, oxygen (e.g., purified oxygen gas), and/or carbon dioxide to the plant according to corresponding delivery schedules. For instance, water and oxygen may be conveyed into the first and second root chambers via a main supply line. Carbon dioxide may be conveyed to a base of the plant via a carbon dioxide delivery ring. In some instances, the delivery schedules may be determined by a type of the plant and/or a growth stage of the plant.

         21 . An aeroponic device comprising:
 a receptacle having an inner area for receiving a plant or a seed;   an enclosure coupled to the receptacle and at least partially surrounding a volume of air;   a root passageway connecting the inner area to the volume of air;   an oxygen source;   a fluid delivery system for providing purified oxygen gas from the oxygen source into the volume of air; and   an oxygen delivery schedule, stored in a memory, for controlling a delivery of the purified oxygen gas from the oxygen source into the volume of air.   
     
     
         22 . The aeroponic device of  claim 21 , wherein the delivery of purified oxygen gas comprises a first delivery, and further comprising:
 a water delivery schedule for controlling a second delivery of water into the volume of air;   the first delivery of purified oxygen gas comprising a first period of time; and   the second delivery of water comprising a second period of time, the first period of time being different than the second period of time.   
     
     
         23 . The aeroponic device of  claim 21 , wherein the enclosure comprises a first enclosure and the volume of air comprises a first volume of air, and further comprising a second enclosure at least partially enclosing a second volume of air, the oxygen delivery schedule controlling the delivery of the purified oxygen gas into the second volume of air. 
     
     
         24 . The aeroponic device of  claim 21 , wherein the root passageway comprises one or more perforations on a bottom portion or a side portion of the receptacle that provide an opening through which a root of the plant or the seed accesses the volume of air. 
     
     
         25 . The aeroponic device of  claim 21 , wherein the fluid delivery system comprises:
 a supply line extending at least partially through the enclosure; and   a tube communicatively coupled to the supply line and extending into the volume of air; and   an opening on the tube for dispensing the purified oxygen gas into the volume of air.   
     
     
         26 . The aeroponic device of  claim 21 , further comprising a vent opening disposed on an outer portion of the enclosure. 
     
     
         27 . The aeroponic device of  claim 21 , wherein the fluid delivery system alternates between providing a plurality of water deliveries into the volume of air and a plurality of purified oxygen gas deliveries into the volume of air. 
     
     
         28 . A system comprising:
 an enclosure for housing a root of a plant;   a volume of air at least partially enclosed by the enclosure;   an oxygen generator;   a water reservoir; and   a fluid delivery system comprising instructions stored in a memory that cause the fluid delivery system to:
 open a first valve to provide oxygen gas from the oxygen generator into the volume of air for a first period of time; 
 close the first valve for a second period of time; and 
 open a second valve to provide water from the water reservoir during the second period of time. 
   
     
     
         29 . The system of  claim 28 , wherein the oxygen gas is prevented from being delivered into the volume of air during the second period of time. 
     
     
         30 . The system of  claim 28 , wherein the second period of time is greater in duration than the first period of time. 
     
     
         31 . The system of  claim 28 , wherein the oxygen gas comprises a first oxygen percentage and the volume of air comprises a second oxygen percentage that is lower than the first oxygen percentage. 
     
     
         32 . The system of  claim 28 , wherein the first period of time comprises a duration between about 30 seconds and about three minutes. 
     
     
         33 . The system of  claim 28 , wherein the second period of time comprises a duration between about one minute and about fifteen minutes. 
     
     
         34 . The system of  claim 28 , further comprising opening the first valve for a third period of time occurring after the first period of time, the third period of time being longer in duration than the first period of time. 
     
     
         35 . A method comprising:
 establishing a root of a plant in a receptacle;   at least partially enclosing a space below the receptacle, the space including a volume of air for the root to occupy;   providing purified oxygen gas into the volume of air for a first period of time;   omitting from providing the purified oxygen gas into the volume of air for a second period of time; and   providing water into the volume of air during the second period of time.   
     
     
         36 . The method of  claim 35 , wherein the space below the receptacle comprises a first space and the volume of air comprises a first volume of air, and further comprising at least partially enclosing a second space below the first space, the second space including a second volume of air for the root to grow into during a flowering growth stage of the plant. 
     
     
         37 . The method of  claim 36 , further comprising providing the purified oxygen gas into the first volume of air and the second volume of air during a third period of time occurring during the flowering growth stage, the third period of time being different than the first period of time. 
     
     
         38 . The method of  claim 37 , wherein an oxygen percentage of the second volume of air increases a first percentage during the first period of time, and the oxygen percentage increases a second percentage during the third period of time, the first percentage being less than the second percentage. 
     
     
         39 . The method of  claim 36 , wherein the second volume of air is at least partially separated from the first volume of air by a divider, the divider including one or more perforations that form a root passageway.
