Yeah, I've had some seed germinating problems, myself. Only White Widow for me, though.

They've been in a cup of water for 4 days, and only one (out of five) have cracked.

But I've been told that some seeds can easily take at least a week to crack, even if the germination conditions are perfect.

Which is ok, because the weather here in Seattle took a HUGE turn for the worse, and I don't wanna be putting any plants (inclduing my flowers and veggies) outside until it starts to get warmer.

It's frickin' June, and the high for this week is supposed to be like 62. So stupid.

But, uh, yeah, I wouldn't start freaking out yet. Just wait a little while more.
