The strain is used to being in sunlight 23 hours a day for 1/2 the year, Matanuska Thunder F___K.
thats kind of a wifes tale
i got family in alaska, and the solstice only give the 23/1 for about 7 weeks, (june 21, or Dec 21 is the 23 hour dark)
so, about 3 weeks on each side of june 21 does it get the 23/1 roughly.'
on march 21, (equinox) it is a 12/12 cycle outside, in N. Hemisphere.
by Sept 21 (equinox) it is a 12/12 cycle already.
so, it isnt 23/1 for 6 months like people think it is, otherwise, it would go from 23/1 to 1/23 in 1 day, then, in march, go from 1/23 back to 23/1. cant happen.
