GeoDome Greenhouse Water Tank

8 Hours
A good way to regulate the temperature in a greenhouse is through a thermal mass. The absorbed heat from the air warms up the water during the day and gives it back during the night. In our GeoDome greenhouse we build a 280 gallon water tank.
We built the tank out of two 4 x 8 sheets of plywood.
We lined the tank first with tarp, and than with 4 layers of 4 mil black plastic
Great for some water plants
