An apparatus for transferring liquid onto the surface of a roller for ultimate transfer onto plants, and a method of constructing a storage tank component of the apparatus. A sponge is disposed in a housing adjacent a roller so that the sponge extends outwardly from the housing into contact with the roller periphery. Liquid is dripped onto the sponge, and excess liquid drains through openings in the bottom of the housing into the storage tank. The storage tank is formed by two plastic pipes bent at a middle portion with an opening between them at the apex of the bend of the top pipe. The top pipe is cut-off to provide an open top complimentary to the sponge housing bottom. Liquid from the tank is recirculated back to the pipe dripping liquid onto the sponge.
