  • Apparatus for accelerating the growth rate of agronomic and horticulture plant varieties
    Patent number: 5056260
    Abstract: Vibration-causing-motion in combination with semihydroponics is used to accelerate plant growth at a faster rate than other current systems. The system of the invention utilizes a frequency of 45 to 500 cycles per second, and includes the use of weights to produce the necessary amplitude for the desired vibration. The system of the invention also may utilize a timing device which cycles on and off throughout the day, every day, to apply the desired amount of motion to the plants over a given period of time. The semihydroponics employed utilizes layers of soil, air and water combined at times with moving water and isolation of the plant roots in soil to minimize root rot.
