Try it for one day...put it in and let it sit for a day...if that results in a satisfactory burn, you're good to go...if not, give it another day...
I have a thermometer with a humidity device that displays the temp and RH in the room where I keep my humidor. If the RH is 50 or below, I'll just set the cigar out on the desk for a day, without putting it in an actual dry box.
Haven't had too many cigars tunnel, canoe or go out frequently when doing this. But I have a larger supply now, so I rarely smoke a cigar right off the truck. I still get the occasional uneven burn, but that may be more of a roll issue.
