Plant growth container
First Claim
1. A plant growth container comprisinginner and outer pots disposed in interfitting relation about upper ends thereof to define a space therebetween, the inner one of said pots defining a cavity for receiving soil and the roots of a plant and wherein the outer one of said pair of pots has an upstanding wall and said inner one of said pair of pots has an upstanding wall with a shouldered rim fitting within said upstanding wall of said outer one of said pair of pots in a tight fit manner;
- heating means in said space between said pots for heating said inner pot to heat the soil within said inner pot and to maintain the roots of the plant warm; and
a thermostat mounted within said cavity of said inner one of said pots for sensing the temperature of the soil thereat and being operatively connected to said heating means for selectively actuating said heating means in response to sensing of a predetermined temperature of the soil.

Abstract
The growth container is formed of two pots that interfit within each other to define an enclosed space. A heater disposed in the space supplies heat via a reservoir of water for heating the inner pot and the soil in the inner pot to keep the roots of an aquatic plant embedded within the soil warm. A thermostat(s) is provided for maintaining the temperature of the soil at a predetermined temperature.

3. A plant growth container comprising
an outer pot having a first base and a first upstanding wall defining a cavity; -
an inner pot having a second base and a second upstanding wall defining a cavity for receiving soil and the roots of a plant, said inner pot being disposed within said outer pot to define a space for receiving water between said first upstanding wall and said second upstanding wall and between said first base and said second base; a heater disposed in said space between said outer pot and said inner pot for heating water in said space whereby heating of the water in said space transmits heat through said second upstanding wall into the soil in said inner pot and the roots of a plant in the soil; and a thermostat mounted on said heater and passing through said second base of said inner pot into said cavity of said inner pot for sensing the temperature of the soil thereat and being operatively connected to said heater for selectively actuating said heater in response to sensing of a predetermined temperature. - View Dependent Claims (4, 5, 6, 7, 8)

9. A plant growth container comprising
an outer pot having a first base and a heat-insulative upstanding wall defining a cavity; -
an inner pot having a second base and a heat-transmisive upstanding wall defining a cavity for receiving soil and the roots of a plant, said inner pot being disposed within said outer pot to define a space for receiving water between said first upstanding wall and said second upstanding wall and between said first base and said second base; a heater disposed in said space between said outer pot and said inner pot for heating water in said space whereby heating of the water in said space transmits heat through said heat-transmissive upstanding wall of said inner pot into the soil in said inner pot and the roots of a plant in the soil; and a thermostat mounted within said cavity of said inner pot for sensing the temperature of the soil thereat and being operatively connected to said heater for selectively actuating said heater in response to sensing of a predetermined temperature of the soil, said thermostat being mounted on said heater and passing through said second base of said inner pot. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A plant growth container comprising
inner and outer pots disposed in interfitting relation to define an enclosed space therebetween, the inner one of said pots defining a cavity and wherein the outer one of said pots has an upstanding wall and said inner one of said pots has an upstanding wall with a shouldered rim fitting within said upstanding wall of said outer one of said pots in a tight fit manner; -
a layer of soil in said cavity of said inner pot for receiving the roots a plant; heating means in said space between said pots for heating said inner pot to heat said soil within said inner pot; and a thermostat mounted within said inner pot for sensing the temperature of the soil thereat and being operatively connected to said heating means for selectively actuating said heating means in response to sensing of a predetermined temperature. - View Dependent Claims (19)
