I would say it depends on the humidity in your climate. I would DEFINITELY buy a hygrometer and use it. Dry incubation does not mean not paying attention and monitoring and managing your humidity, it means shooting for a different number, but that number will not maintain itself. You will need to add water, plug and unplug holes, twist the control, check seveal times a day, keep an eye on the weather channel same as people who run higher humidity. If you TOTALLY lucked out, the weather in your area would be completely conducive to dry hatching with minimal interference, but I would not trust Mother Nature to do me any favors, especially this time of year when heaters and fireplaces dry out the air in many homes, and temps fluctuate from day to night while we sleep (if we are thrifty and energy conscious) You will still need to monitor temps, watch the water, do all that stuff. Good luck with your hatch. The more you do it, the better you get at it as you find out how your particular home environment affects the humidity and temps inside your incubator during the daily cycle in your home.
