I have roughly 40 seeds germinating. 20 have sprouted for the past two days, and the other 20 are showing progress. My question is they have gone 2 days without light, how much longer can they go? Should I turn on my LEDs yet?

Some of them I found growing upside down in the Rapid Rooter.

What is the point of not turning on the lights during the germination period?
