A hydroponic feed indication apparatus is disclosed. The apparatus may include a hollow body having a distal body portion and a proximal body portion. The distal body portion may be inserted into a tree stand, and the proximal body portion may receive fluid via a proximal body portion top end. The apparatus may further include an anode electrode and a cathode electrode disposed at a distal body portion exterior surface. The anode electrode may move along a distal body portion length via a first elongated slit disposed on the distal body portion. The cathode electrode may move along the distal body portion length via a second elongated slit disposed on the distal body portion. The apparatus may further include a fill level indicator disposed on the body. The fill level indicator may activate when the fluid shorts the anode electrode and the cathode electrode.

A three-joint linkage lifting device with built-in chain for Christmas tree, comprising an outer tube, a middle tube, an inner tube, an upper fixing sleeve for the outer tube, an upper fixing sleeve for the middle tube, a lower fixing sleeve for the inner tube, an electric lifting assembly, and a sliding hoisting rope, wherein the Christmas tree lifting bracket is configured to be an electric two-stage lifting bracket, and the components of the Christmas tree are sleeved outside the bracket, so that the Christmas tree bracket can be lifted and lowered by pushing the screw linear pushing device of the electric lifting assembly, the sliding hoisting rope is fixed on the electric lifting assembly, and when the middle tube rises, the sliding hoisting rope is jacked up to slide and pull up the inner tube synchronously.

A decorative light frame device used for accommodating and supporting decorative string lights to give a resemblance to, for example, a Christmas tree. The device includes a base ring and a base plate for support, a center post having at least two columns wherein the bottom column is attached to a tilting means such as a pivoting bar or a tapered pin for swiveling to stabilize the frame when the frame is positioned on a slope. A pair of arms attached to the base ring is fastened to the center post for supporting the post. A plurality of different sized rings is detachably positioned on the post. A plurality of decorative lights are woven across the hooks of the rings to resemble, for example, a Christmas tree for decoration and illumination.
