It also conducts physical comparisons of sphagnum moss from three countries, to provide a reference for growers. It also explores the flow of water within sphagnum moss. Not to give in irrigation circumstances, the media will only be damp evapotranspiration, the gravity of the water caused significant changes to the concept of the experimental set up two groups of samples. 1. Samples placed on the humid atmosphere, 2. Volume of samples will be wet and test samples at different depths (2cm, 4cm, 6cm, 12cm) of the water changes to the unit time to speculate the surface evaporation of water.The results show that in Chile sphagnum in the Institute set up under the conditions of a better water-retention capacity. Sphagnum from Chile and do changes of water, and the results of the test results showed that medium gravity caused by water flow down, and then to the surface of the medium that is derived evapotranspiration to 0.68 × 10-7 (volume of water cut Rate / per minute).
