Sun- and Shade-Harvesting Cisterns

How rainwater cisterns can be placed to harvest the warmth and light of sun in cool/cold times, while harvesting cooling shade in hot times…

This makes the rainwater in the tanks go further, because the garden plants’ water loss from evapotranspiration—and thus the water needs of the garden plants—are reduced by the cooling shade cast by the tanks at the hottest time of the day.

Winter garden production is also enhanced by the placement of the cisterns (in relation to garden and sun) creating a warmer microclimate on cold mornings, which burns off frost sooner and gets the plants growing
