Hey funderdank,
Usually planting the seed point down 6mm beneath the soil is enough to drop the shell and prevent J-root (this is my go to technique for raising seedlings..I dont use the paper because disturbed roots dont grow so well and curved roots can become j'ed (j-shaped) which hinders growth immensely and preventing plants from acheiving their full potential by strangling the root and often pinching off the main water line altogether. I digress (I hate J-root a large proportion of all plant issues can be tracked to the health of the roots) sometimes if confident and you have good eyes or your glasses on you can use a small pointy tool to coax the husk to split and come away..this is very risky and I still fuck it up from time to time when this happens to me..and it does sometimes I water too hard and the seed becomes dislodged and floats to the surface then sprouts..grrr lol.
It an easy fix...but risky. Or you can just leave it and keep the husk moist and the plant might bust out...could be a 10day process though.
I hope that helps and wish you very Sticky Buds1
