I need some help with planting seeds in Oasis cubes.

I planted some seeds in Oasis cubes and I pinched the whole closed. Now when I check it out it seems like the Oasis might be to hard for the baby plant to pop through. Was I supose to leave the hole open?

I think oasis cubes are much like rockwool. If that is correct then you shouldnt have a problem. and yes the seed needs to be covered to stay moist and dark. How long ago did you plant them?

Just last night. Thanx for responding. I'm just a worrie wart about these new seeds (I paid $80 for 5 of them, Super Lemon Haze) Ive always used clones. I have some other seedlins I put in jiffy plugs about a week ago. They are in soil in cups now. Thanx again.
