Please help - need to know asap.

Is it true that when you're germinating seeds if the root tip (white thing) grows longer then a half inch it's not viable, and won't sprout if you plant?

 

Are you sure? I germinated six seeds and three of them are nice and short and then the other 3 are over a half inch long. I need to know for sure, because it's a waste of my time to carry an extra 3 pots and a bag of soil if they're not going to sprout.

 

I heard it in a growing video I watched on YouTube, damn good thing I checked here first, I was going to throw those seeds out. (3x Early Skunk feminized)

Thanks guys!

 

Thanks man.
