LED light busted: Seedlings lost 4 hours of light

[Terepeneterrapin]

I've probably flooded the forums with my newbie questions, but appreciate everyone's helpfulness so far.

Something unexpected happened, as title states. While adjusting my grow light (Samsung Quantum Board) the connector snapped off the soldering points. Couldn't have happened at a worse time as my seedlings JUST germinated. Just wanna ask, how bad would the 4 hours of darkness (+6 from my 18/6 schedule) really damage my plant. Im planning to get the LED resoldered later on but plants are gonna do without 4 hours of light.

Additionally, anything to do to recover etc.

Not going to matter with seedlings, they don't really need a ton of light for a few weeks, I used to do them with a pole lamp and regular light bulb for first week or so.
