Title: Horticulture device for rotating plants due to transpiration and evaporation of moisture

Abstract: A container for plants is rotated as water is evaporated and respirated therefrom due to the interaction between a compression spring and linear-to-rotary motion mechanism. The compression spring is disposed between the container and a stop on a support shaft suspended from above wherein the support shaft has a spiral portion thereon and the container has a slot for receiving the spiral portion. As water evaporates, weight on the compression spring is reduced and the container rises upwardly on the shaft in relation to the stop on the shaft. As the container rises, it rotates slowly. In an alternative embodiment, the shaft is rigidly fixed to a base upon which the container rests and the container includes a soil containing pot which may move relative to the base. The compression spring is disposed between a stop on the shaft and the soil containing pot to bias the pot upwardly when there is no water therein so as to raise and rotate the pot with the linear-to-rotary motion mechanism as the water evaporates.
