how long after potting till plant breeches???

i popped a few auto seeds and planted them and only one as breeched that was about 3 days ago the rest haven't yet. should i just let it do its thing or is there a possibility that they won't breach the coco?

Very few will take longer than 14 days. I prefer germinating directly in a medium so the new root kan find the P it needs to develop.
Whatever you do, don't scratch around looking for the seedling.

ill bare that in mind with my next crop man thanks for the advice.

Put some cling film over the top of the pots to help retain moisture, for a auto i would say a week but some conditions can make things take a little longer, at 14 days if nothing then pull them out and start again.
