Dickeys 2x2 what method do you use.

Hi all. I have a new Dickeys 2x2 and have read most of the threads on them. I see that some folks are going by Dickey's suggested temps and humidity and others are not. Some have the auto humidity sold by Dickey and others don't. I'm hoping to get input from others and to learn what methods your using and what hatch rates your getting. I've yet to set or hatch eggs so this is all new to me other than what I've read on the forum. I did not buy the auto humidity system and am wondering if I need to.

Thanks,Cody
