lowryder #2 seeds not sprouting after 40 hours?

so im trying to sprout 3 lowryder #2 seeds via the paper towel method, and its been about 40hours since i first put them in and only 1 is showing a root, and its a very small one. the other two seed's shells have cracked, but no root.

they're wrapped in a layer of paper towels, soaked in distilled water, in a ziplok baggie, and i stuck that inside of a thick padded envelope, covered by a small blanket to keep dark. i set this setup on top of my laptops power supply to keep warm.

im probably just being impatiant/paranoid, but is this relatively normal to be taking this long? i know seeds can take anywhere from 24hours to 72hours, but i guess i just expected them to be sprouting by now, as my last seeds didnt take nearly this long. any advice would be helpful. thanks!

You say that you know that they could take up to 72 and you're freaking after 40? Relax, have a seat and enjoy the show. Have a bowl or two while you're waiting, it'll be worth it! Here, have a hit on this....

60hrs and STILL no white popping out =/

A watched pot never boils. This is true for much of growing. It is a slow process.

relax man. if there room temp place them somewhere slightly warm. Everyone seems to like cable boxes. perfect temp. try that and don't worry until a solid 4 days. warm them up a bit. good luck. i also grow lr2 keep me posted

i just had 2 lr#2s pop out in like 8 hours soaking in a bowl of water under a soaked rockwool cube, idk

I popped 8 straight into soil. 7 took 4 days to show, one took 8 days . Patience is your friend
