It got down to 34 degrees last night, plants were cover, still looks good around noon today. High now is 55. Another night of 34 low's tonight. Lots of north wind, but cover works well, and plants seem to steal be growing and doing well. I don't believe I will have a problem as long as I can keep the Cu-stop-0 out of my yard. Good luck, and happy growing. Thank I'll will go plant some mines.
