It would then shut down around 93 or so? No I would not the other hydrofarm issue is the reading is horribly off. I have tested a number and I have not had one that was correct. They all read wrongly. Johnsons and rancos both only have a one degree up and down shift and are better for accuracy. proportional units are even better again. I don't usually suggest using a hydrofarm they just have such poor accuracy and swing that makes them iffy.
26.9ºC = 80.42ºF the hydrofarms in the picture are 83.8 82.4 and 81.6.
