Using the Thermal mass of water for greenhouse heat exchange

Scribble plan to practical success. The pump sends water around 30 metres of pipe in the greenhouse ceiling & back into the side butts.This slowly heats up the water during the day.This has two uses; cooling the greenhouse down on hot days & releasing ridual heat during the night
