Hey I just read this post for the first time but I have five plants that are 14 days old as of the 1st of December and these plants are growing faster than I was expecting, they had tap roots about an inch long in one day but I kept them germinating and by the second day they were out of their shells and had the round starter leafs. I put them in rock wool and they are growing greatly, I think. The only thing I regret is that I put all five in the same rock wool but I'm not to worried. BTW I'm using one 42w (150w) cfl.
