Right seeds for a beginner hydro aeroponics

I want to germinate in rockwool but none popped. I need help.

I have used the wet paper towel method for 40+ yrs. Works IF you check the seeds every 6 hrs.
Healthy seeds will hatch in 36 hours…once the tap root is 1/4"+ transfer to rockwool. Keep moist. Once root has grown tru the rockwool, transplant.
