using an air stone to control solution temp

[dunno]

RON, I have a dilemma. I have a 55 Gal. barrel buried in the ground for the nutrient solution. The average temp here is 85-90 F. Would using an air stone in ambient air raise the solution temp to the ambient air temp? Would it make a difference?

No different unless you put the air pump inside a refrigerator.
