In winter here it is veggie growing season. But we do get cold nights fairly often, so they help keep the veggie plants warm and producing. Jugs that are clear or translucent, I fill with water and used coffee grounds to make the water dark. then use as heat sinks all around my yard, and around my Earth Boxes. White jugs I paint with a dark color spray paint.
I also use them as scoops, and they make great bailers in boats, too!
