Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
96 words
Apparatus for watering and humidifying plants comprising: a tray for holding water, support means within said tray, a mat on said support means at least a part of which is adapted to dip into the tray to communicate with the water therein, said mat formed by a composite of a lower layer of a fabric of a pile-type material to conduct water by a wicking action and an upper layer of a harder finish than the lower layer to conduct water but at a lesser rate than said lower layer and to protect the lower layer.
