Here is the question I received by email - assume it came from a viewer on PB. You guys take a shot at answering the question.

Question -

I'm in Southern Missouri you have any idea how deep a hole it would take to have a temp of 65 degrees, our summers are brutal into the 90 degree temps. Im debating using aeriation kit at 10' depth when temps drop down at night. I have no idea where the thermocline depth is here.
