Germination to open or to close tent?

Good morning, Growmies quick ? Im currently in the germination stage can I leave my tent door open or will the light leakage be harmful?

It will be fine ,nice set up

Light leaks are really only detrimental during flower stage.

What about dark hours in veg stage ? Total darkness needed ? Seems not from my readings here.

You could veg plants on 24hrs of light if you wanted to.
