摘要: A device for automatically watering potted type plants has a shallow reservoir base/tray capable of holding water and also supporting at least one previously plant an inverted container (such as typical screw top jar turned upside down) containing additional (and/or other nutrients). specially adapted support base is used to keep the bottom (where opening located) slightly above base/tray. The can have ribs or rails raised lowest part tray (but lower than in container). detachable lid with hole. attached filled (not yet inverted) are fixed while hole covered by owner's finger creating partial vacuum such that will only flow from when level tray/base drops below opening.
