Hygrophila polyspermous - unassuming and recommended aquarium plant that is able to withstand these conditions of detention, where many aquatic plants die. It grows well in a soft, but especially prefers hard water at a temperature of 22 - 28 degrees C. With intense light from the plants develop powerful elite. In poorly lit aquariums can be seen that although the plant is developing normally, but the pace of growth is slowing sharply, the shoots become smaller and therefore less decorative. The soil for plant nutrition plays a secondary role. Its quite satisfied with washed sand. Additional CO2 saturation in general though, and supports the growth rate in the tank for this type is not necessary.
Gigrofilu Indian group planted in the front or middle of the aquarium term. Shoots due to their rapid growth must be trimmed every two to four weeks. Reproduction of lateral shoots. This type gigrofily particularly suitable as the first plant in the newly Being equipped aquarium. Formation of inflorescences occurs very rarely in surface shoots.
