Yes, that is very close to what I use. I bought the cheaper ones by a different company and then bought the fan attachment. That one seems to have a fan built in. I started a poultry business years ago, kept buying the small incubators because I could not afford a large one. Then bought a larger cabinet incubator and the little ones just sat till I tried using them for ghost pepper germination. I have used them with those little peat pellet things but what I really like is the twisted up newspaper pots ( google Pot Maker Newspaper) because I have a lot of sitting time in the winter to make my own pots. That and I am big into reusing / recycling.
Anyway, they have windows on top and come with thermometers. You put the thermomiter where you can see it threw the window and adjust the heat. People will surly argue because all seed is different, but I have had best results with ghost peppers up around 98 degrees. Not sure what other peppers want. My main difficulty has been with ghost peppers and even then mainly because we do not keep the home as warm as most. I am a cheap bastard and propane has been very expensive.
