Abstract
A planter has a reservoir for water which is connected with the space below the reservoir in the planter housing by a valve seat cooperating with a valve plate on a stem rising from the float vertically displaceable in the space below the reservoir. The stem extends through the reservoir and up through the planter wall to have an upper end whose position signals the liquid level in the planter. A clamp on a sleeve carrying the valve plate can be released to permit axial displacement of the stem relative to the sleeve and adjustment of the spacing of the float from the valve plate to vary the level maintained in the planter.
