"At about five feet down, ground temperatures lag three months behind seasonal air temperatures."

Having trouble finding an exact formula for heat dissipation through the ground. I could take temperature readings, graph them, then come up with an exact formula for "correcting" my soil temperature. I'd estimate we have a 15 degree seasonal difference. If there is 3 months lag soil temps 5 ft down should be 35 then 50 then 65 then 50. Offset by 3 months.... we would never hit 65 five feet down maybe 60 at most... Basically it is all about getting temps into the 50s hopefully 60s. Because in the 40s the roots will do nothing. 60 degree ground should be my goal.
