although over here Mother Nature is hesitating between Fall and Spring (day temps are 60F and at night it is 50!.) I have set up a grow tent in my garage to put my seedlings in.
Who knows, we may get some Winter after all

During the trialrun the last 2 day it got 70F in the tent during the daytime when I have 2 lamps on, and 58F when they are off.
As is is 'colder' in the garage at night, I am thinking about switching day and night: putting the lamps in my tent on at night and off during the day, so the temps when it's dark inside will be higher

Would that be beneficial for my seedlings?
Or does the night temp not matter (as long as it doesn't get réally cold)

Traditionally it has been thought beneficial to have temps lower at night than during the day. The idea was that respiration at night (temperature related) would not then gobble up all the "food" produced during the light period by photosynthesis. I saw something recently that suggested this may not be necessary for at least some plants but for the time being I would stay with cooler during the hours of darkness to be on the safe side.
