Under the conditions of the aquarium, as well as in nature, there is a seasonal growth hornwort. In winter, growth is slowing, Hornwort sinks to the bottom and saves only the apical escape.
Hornwort can grow in any aquarium : coldwater , tropical and warm temperate. At high water temperature 24-28 ° C, the plant develops extremely rapidly. Particularly favorable for him moderately hard water with a neutral or slightly alkaline reaction. In soft water with acidic Hornwort growing somewhat worse. Plant needs a fresh, often substituting for water. When the turbidity particles quickly settle on its hornworts and spoil its appearance. When this plant tolerates appearance on leaves plaque and fouling enough firmness. Contaminated branches should be rinsed in clean running water and put back into the aquarium.

In autumn , when the lighting is deteriorating growth slows hornwort, and stems fall to the bottom. While maintaining high water temperature and artificial light growth continues for quite some time, but later a rest period still occurs. By reducing the water temperature to 12-14 ° C in the plant saved apical buds that develop new stems in spring .
Hornwort very easily propagated by dividing the stem. To get a new plant, it suffices to take a very small piece of the stem.
