Abstract: An indoor plant growing system that includes a casing subsystem, a containers chamber, a water containers subsystem, an ultrasonic humidifier, a ventilation system and a lighting system. The casing subsystem includes a roots chamber, a plants chamber and a partition element that separates the roots chamber from the plants chamber. The water containers subsystem includes a humidifying tank, a terminal connection to a main water thank and a water pump that pumps water from the main water thank to the humidifying tank. The ultrasonic humidifier is positioned inside the humidifying tank. The system may include a fertilizer spray system or a cooling system for cooling the water in humidifying tank. The system may include a rotational mechanism which is designed to rotate the casing subsystem so that the plants will grow downward.

Abstract: Method and apparatus for the disinfection of soil. Flames are generated into the soil, at the desired depth and at predetermined distances between them, so as to produce a relatively uniform heating of the soil. The flames are displaced within the soil along desired trajectories to cover any desired agricultural area. Narrow trenches, such as narrow clefts created in already plowed soil, are created in the soil and the flames are advanced along the trenches concurrently with them. The flames may be produced by igniting streams of liquid or gaseous fuel that are continuously fed to the desired depth in the soil.
