One of my seeds has cracked,but instead of the seed comes out,the root came out.And the seed stays inside the rockwool.May be it came upside down?What i can do?Pls help me ASAP Thank you in advance
Sounds like you planted the seed upside-down. Do this next time: plant the sees pointy side facing DOWN. Or better yet, plant the seed on it's side, 1/2" deep, in a peat pellet.
