Do you have any pictures or possibly more information on the germination process like grow room parameters and so on possibly to identify the issue a bit more.
I germinate in my office so I don’t forget about them. Damp paper towel in a ziplock placed on top of my Mac trash can for warmth. Typically get taproots within 24/48 hours. Quickest has been 12.
From there I put seeds in starter cups and a humidity dome under a small grow bulb on a side table in my office until it breaks soil and presents itself. Then into a tent that is 70-76°F 50-60%RH.
