Direct in a home made specialty seed raising mix (soil), in 4 inch wide by 5 inch deep black plastic pots.
This size of pot is good for about 3 weeks growth.
Have been doing so for 35+ years and it is surprisingly simple, just don't let the mix dry out.
I have never covered the pots with anything and water them with a hose!
Otherwise, using rockwool cubes is super simple too and almost fool proof.
I have done a tutorial on the rockwool cube method in the "germination week" in my "cannabis conundrums" diary if you are keen for an insight to this method.
