Title: Hydroponic feeder and cooler

Abstract: An apparatus and method for supplying an aqueous liquid for plants utilizes a reservoir having inside walls. There is a conduit for discharging the liquid so the liquid flows along walls of the reservoir. There is a cooler for cooling the walls so the liquid flowing along the walls is thereby cooled. For example, the reservoir may comprise a converted chest-type freezer unit. There may be an opening in the walls of the reservoir and the fan located in the opening to direct air into the reservoir and aerate liquid therein.
