Dwarf baby tears (Hemianthus callitrichoides or HC Cuba) are actually pretty predictable plants, and they are quite easy to grow as long as a few basic concepts are followed. These are the 4 main factors that will influence the success of the HC carpet. In ascending order from easiest to most difficult to control. Temperature, light, planting technique and co2. Draft baby tears, just like most aquatic plants, can actually survive in a huge range of temperature. The sweet spot is somewhere between 20-24 degrees Celsius. At colder temperatures, the HC just grow a bit more slowly, but they still survive. At hotter temperatures towards 30 degrees, you can still have nice carpets, however, growth may not be full and you can face other problems.
