When I took a small gardening class for working in a nursery many many moons ago I recall them saying that the ever so fine hairs on each strand of root including tap roots,if damaged can stunt/shock or even kill if disturbed enough.I have no clue if that applies to Herbal Seed roots..I'd think to a degree but dunno.and thats why I personally never use paper towels.prolly the only reason.cuz I suck at growing i try to avoid any chance of jackin stuff up.LOL!
tweezers and lightly cover I doubt your gonna do any real damage to the hairs though bro.
