I wouldnt say its getting better just yet. I think Im going to need to use a space heater either way during the lights off cycle which is a definite bummer as it will cost me quite a bit of money that I had not anticipated as a cost. I will just have to see how much warmer it stays in there with the fan off, I dont anticipate that much warmer but we will have to see... will keep you guys posted on this one.
