I was following this thread with interest, but am wondering what the
tempatures should be if one, like me, is using HPS lights to extend
the days into 12 hour days and as supplemental lighting during the
winter months?.

Hi Everyone,With autumn/winter upon us,my first growing in the greenhouse I
have a question about how you control temp with the day or just a set amount
of temp(8 hours a day, for example) regardless of daylong.
