Is that a heat stick you’re using in the GF.
I have version 1 of the grainfather and bought a heat stick off HBT. Best thing I ever did. Cut my ramp times down big time. The first time I used it I had a boil over (not paying attention). If you have a grainfather and are considering it I highly recommend it! Definitely saves time during your brew day and you can have a violent boil if you so choose.
