Donât worry about it. 63% is no big deal and for 8 hours it is absolutely nothing. In fact, some folks like their cigars at 63% RH all the time. Your humidor will slowly return to a higher RH and if, after a few days, it doesnât then add some water to your humidifier.
A light-year (abbreviation: ly), sometimes written light year, is a unit of length used informally to express astronomical distances. It is approximately 9 trillion kilometres (or about 6 trillion miles). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year. Because it includes the word year, the term light-year is sometimes misinterpreted as a unit of time.
a Light Year is not a unit of time, but a unit of distance. One light year is equivalent to the distance traveled by light in one Earth year. 1 light year is equivalent to 9.461 x 10^12 kilometers. If you are not used to scientific notations, thatâs around 9,461,000,000,000 kilometers in distance.
