I had some dark seeds that did not grow for me more then once. I tend to think the lighter brown/greyish seeds work best for some reason. I have not had the best of luck using the paper towel. I read an article awhile back "last year" and also seen it re-capped in either hightimes or growers in last month issue. Both articles stated to skip the wet paper towel. It said to soak the seeds for 24 hours it a cup of water. Then place the seeds in a dixie cup "one seed per cup" using your soil mix. Place the seeds down about 1/2 inch in "loose" soil. Put the cup on a gemanaztion "no sure of spelling" pad at 80 degrees. Check soil every 12 to 24 hours to make sure it does not dry out. In last month article he said he did the paper towel and the soil side by side with seeds from the same shipment and the seeds that were put right into soil grew better and faster from the start.

I have been using the above for about a year and it works great. Once less transfer to stress the plants.

But if you decide to stick with the paper towel sometimes it takes several days for the seeds to pop
