A plant growing unit comprises a plant growing portion and a fertilizer-producing portion containing earthworms. The earthworms produce the fertilizer from vegetable matter and the fertilizer is used for growing the plants, preferably by the hydroponic technique. In a preferred embodiment, the fertilizer-producing portion is constructed also to permit the behavioral pattern of the worms to be observed.
