These improved stands taper down towards the top to allow more room for the leaves to the plant compared to the stands from rise. There is also a center strut which provides a central point for clipping the ties. The stands slide under the lip of the net cup and include reusable ties to help support plants that are struggling to stay upright on their own. This is for supporting plants and is not a trellis. Compatible with all rise gardens. This item is made of pla and petg.
