Also measure environmental factors by measured values are air temperature, soil temperature, soil moisture, relative humidity of the air. Light intensity and acidity (pH)
.Determination of relative humidity in the atmosphere can be made by using the tools wet-dry thermometer by the hanging in the mystery to norepinephrine นือ ground about 1.5 meters. The value negative, then the compared to the scale tool. The air temperature is obtained by viewing data in parts of the dry thermometer determination of soil temperature by using thermometer.10 cm, then the thermometer plug into the left about 10 minutes, it will read the temperature value measured and measuring the light intensity. Do it by using the lux meter by measuring the light intensity at the same time, which is between 11.00-12.00.
