I am going brew a partial mash Double IPA today. Can't wait! I've read a lot of threads about temps while fermenting and how it can increase 5-10 degrees. I have a fermenter and a stc-1000 temp controller I built. I usually insulate it and tape to side. Never had problems but I can't help but wonder if the temps are higher. I'm gonna try and run a digital thermometer down into carboy and still tape the controller probe to side. Test it out and share my findings. Anyone care to add if this would cause an issue with fermenting. I would just sanitize the probe. Here's some pics.
Thanks and cheers.
