So in my OCD thoroughness i was checking the almanac for my area to see when the sun rises and sets. It turns out that the time i was planning to move the plants outside, the days are only about 13 hours long from sunrise to sunset. I am getting a little worried that that wont be long enough to start good vegetative growth. Here's the information i'm looking at.

SUN
Begin civil twilight 6:45 a.m.
Sunrise 7:11 a.m.
Sun transit 1:40 p.m.
Sunset 8:09 p.m.
End civil twilight 8:34 p.m.

Can anyone help me out here? Should i be worried?
