slow to sprout - going to be duds?

i am trying to germinate seeds that i made in a cross. there are 12 that i am trying to germinate. 3 sprouted between day 3 and 4. it is now day 6 i think and still only 3 sprouts. i uncovered a couple 2 days ago and saw them cracked with small tails...but they still have not sprouted. should i just get rid of these seeds? they going to end up being dud plants without vigor?

anyone with experience with this? the cross is lr2 and ww

Those sound like some promising seeds. I wouldnt toss them. Sometimes seeds take a little longer to germinate, ive had ones pop at 10 days in the paper towel. Dont give up on them just yet, keep hope alive.

good to know senor. thanks
