No right or wrong method, soooo many ways. I use shot glass and cotton pad (per Home Grow TV). Have used paper towel also. I am going to just drop in water and wait for tap root on my next run. Just go for it. My best advice in general, just stay out of the plants way... fight the urge to do too much. My problems seem to always be associated with something I did instead of didn't do. Cheers mate... good luck! Oh, handle tap root with extreme care really don't handle the tap root at all. Anyway, just be a little cautious at the planting stage.💪
