his green house uses recycled PET bottles to store water in the walls. Because of the low thermal conductivity of water. The water is cold in the morning, but it feels warm at night. Water absorbs heat when there is sun, and it dissipates heat at night. Using this characteristic of water, the house has the function of automatically adjusting the temperature.
