Watering depends on the external environment

Due to the different materials used in different places, it is absolutely impossible to talk about watering unilaterally without talking about plant materials. Generally speaking, places with poor ventilation and high humidity are suitable for coarse plants, while places with good ventilation and low humidity are suitable for fine plants or mixed coarse materials. The author has done experiments on plant materials, using two orchid pots of the same volume and different materials to put the same plant materials in the same place. Chu-Han mud pots are easily watered after 2 days, while plastic pots need 15 cents for 16 days to water. It is evident that water evaporation is greatly affected by the external environment. The water evaporation of coarse and fine plants is 3-5 times, and due to the influence of ventilation, weather, humidity and other external environment, the water evaporation varies greatly. The watering problem is that experience is greater than knowledge, not personal experience but not the true meaning. (song Mingyuan, Anhui)
