She still has her socks on?

Did a dozen 3wks ago and half were like this.Just don't put more than a couple of grains of coco on top.Due to putting the seed in the final big pot I use a 1 litre left over plastic bottle with the lid on for a few days and once I see the first true leaves take the top of for a couple of days before removing completely.Its the perfect environment and saves buying plastic conches at £5 each.I always soak my seeds in water.I didn't eve take the seeds out this time,just filled that little vile up with water for 24hrs.Half had broken the shell by the time I put them in paper.Is that a bit of shell on the tip of that root?Iv not seent hat before but wouldn't worry.Seeds are amazingly strong.They can sit there for years and a little moisture and bang.

leave the paper towel just damp and not wet with excess water

Make sure your humidity is high in the 60s 70s. So the shell can shed
