Hi Aaron,
Seedling Sarracenia are very easy for winter, just drop their
daylight down to 10-11 hours/day for about six weeks. They will
enter dormancy during those weeks. After that, raise the day length
to around 13 hr/day and they will come out of it on their own within
a couple weeks or a month. Then 14-15 hr/day for summer growth.
