Ok so I'm germinating my 6 Purple Ryder seeds. Using WPT, placed in zip lock baggy, placed inbetween folded tshirt and sitting on cable box for some added warmth. It's now been 72 hours. Well 2 have sproutted root tips and I placed them in soil. Now the 4 remaining, 3 havent cracked at all and 1 has cracked and I can see the root tip but it hasent really come out of the shell I guess you could say so I figured it needed to come out some before I dropped it in soil. I've never seen seeds really take much longer than 48hrs, should I be concerned?
