Guys it's probably been said before but I am new so any advice would be great. I am looking at the st1000 as it is a cheap option, but I'm not 100% sure how they work. I have a fridge/ freezer combo that I want to use the fridge section for a fermenting chamber. If I buy a st1000 will that control the temp by itself or do I need a heater to go with it? I think I have read you just plug the fridge into the st1000 set the temp and your away? Can someone tell me if I need anything else to make the st1000 control the temp in my fridge for fermentation. Once again cheers.
