I don't know why, since there seems to be an awful lot of people who do the "jug" thing, but I just can't see how the sun heating black plastic jugs of water can be of any help at all in the fall/winter months. Some of you who do this will have to explain to me how this works "effectively". Let me give you an example and then y'all can explain it to this dummy. Next Wednesday, the low that morning is going to be around 20 F with a wind chill in the mid to lower teens. The high will be 41 F! It will be sunny and cloudless the entire day. How will the sun heat those black jugs during that day? And IF the water is indeed warmed, what will the temperature by of this "heated" water. Lastly, how long would that warmth last when the low Wednesday night to Thursday morning will again be around 20 F?
Carol, I think you will love the affects that the solar blanket material affords you. I have posted numerous comments on what the solar blanket material has done for my greenhouses and will soon add another layer for (hopefully) far greater heat retention in those greenhouses.
