The temp is constant. The room temp is the variable that affects it. So place it somewhere with a stable temp and insulate it a bit if you need to raise the temp or raise the lid a bit if it is running hot. Good luck

Hi, My son has a newer version of this. I just started a test run in it to see what happens. Most say they are junk. I plan to put it to the test. I'll let you know in 21 days how it goes.
