i think most use the paper towel technique. I do but also instead of just water i add a drop of super thrive to the water.. not sure if it makes any difference, currently have 5 white skunk seeds in - after 24 hours first one cracked, then day 4 (today)another is starting to crack but no signs of the other 3 so far. they went in on the night of 26th.
But some have said the thrive helps germination.. not sure really if it does yet but have never got one to crack in 24 hours - more usual of about a week of being in the paper towel...
