ok now that the tstat is running i have a new problem i have some 16 qt tubs some 28 qt and some 41 qt tubs in my rack the 16s are a perfect 91 degrees but the 28s are like 85. now my question is i know if i leave the aspen in the 16s and put newspaper in the 28s and 41s it will raise the temp in them. now can i use printed news paper. i see ralph davis and 8 ball all use unprinted is there something wrong with printed will the ink harm the snake?
