Is it ok to drop my fermentation temperature?

i have the probe of my thermostat stuck to the outside of my fermentor, with some closed cell foam over the top. It seems to work ok and I think that having closed cell foam insulating the probe from the ambient air temp means it will be getting a reasonably good reading of the actual temperature of the liquid in the fermentor. I have the probe attached about half way up the fermentor so I am taking the middle temperature.

 

By the way, are you sure that the thermometer on your fermentor and the thermometer on your thermostat give the same reading at the same temperature?? It may be that at 18 degrees the fermentor thermometer reads 22 deg??

 

If it was me, I would stick the thermostat probe to the outside of your fermentor with something to insulate it over the top.

I have one of those stick-on digital thermometers on the side of the fermenter and it consistantly reads 4-6 degrees warmer than the thermostat probe in the same spot (insulated with foamsimilar to Ralph's).  I'd definitely trust the probe reading over the coloured strip.
