AsNoriuanswered grow question 2y ago A week in napkin is more than enough for 99% of seeds.you see no tap root - bin it and start all over.
Putting seeds directly into medium can prolong sprout, but still 10 days max, no action - you restart.
Had one seed wake uped on day 14 directly in soil, but thats only case, most are breaking soil by day 3-8 since seed touches soil.
Make sure napkin always moist, put it into zip bag, away from any light, roots hate light, BUT with constant +25 Celsius temp.
People use even heating matts.
Restart and hipe all goes well !
