Yes , if your jars/buckets start to raise temps after a few days , not just a few hours, then its starting to ferment and needs more oxygen, so you would turn or dump out like MICH says. Same principle in composting bins. As they heat up the bacteria is rapidly growing/eating/breeding.
I use the jars to even out the moisture levels. (sealing the jar and adding heat will even out the moisture much faster then room temp but i dont like speeding anything up unless its too wet)
Some of our favorite terpenes have a "burning point" of 70-80f so to me , its essential to keep the temps fairly low (65-75) i dont always do that but thats my preference. My personal palate is different from most ,.,.,, i like my herbs
fresh and skunky. 2 or 3 weeks on the road kill strains and longer on less road killy phenos. After 6 months or a year , its a little too smooth for my liking.
