摘要： A system for providing a liquid to a plant or tree stand comprising a liquid reservoir connected via tubing to a liquid control assembly having a liquid level control section positioned on the lower end of an adjustable vertical section with straps for attachment to a tree. The liquid level control section comprises a lever arm/float assembly positioned within the tree stand for maintaining a predetermined liquid level within the tree stand. As the liquid in the tree stand is depleted the float drops and the opposite end of a float lever arm penetrates a channel raising a metal ball which permits liquid to enter the tree stand through the liquid level control assembly connected to the tubing from the reservoir. As the liquid rises in the tree stand, the float is forced upward causing the opposite end of the float lever to drop resulting in the metal ball lowering to seal the channel thereby stopping the liquid flow into the tree stand.
