Question on starting auto seeds outdoors and the effect of upcoming cooling temps.

I just watered some auto seeds outdoors (on-site of my guriella project) temps have been 80 degrees (f) duuing the day and mid 50's at night, and that will continue for a couple more days. After that, we are expecting a cold front. Temps will be low 60's daytime and mid 40's at night. My seeds are in peat cups, in starter soil, inside a plastic terrarium with the vents on top fully open. Does anyone know what effect those temps will have on my autos? Should I try to bring them in before the cold front? That would be a huge pain. The Auto strains I am working with are Afghan Kush Ryder, Auto Sweet Tooth, Think Different and Critical Jack Herer. Anybody know anything about this?

I would bring them in if you could. Last year we did a few early in the season due to the crazy early spring, then the weather went sideways on us early in veg phase, they never really recovered. The first 3 weeks are pretty critical with autos. Yields were low from them...I'm pretty sure we did at least one afghan ryder and one critical jack auto.

I should mention that it was our first time outside and we did encounter other problems, but I've grown autos bigger under cfl's than those we did outdoor.
