Help! Question on germination and seedling production

I am attempting my first grow and germinated 7 seeds using the paper towel method. After 2 days all were showing long tips that have broken through the seeds. The paper towels were still moist so I am not fearful that the seeds were dried up.
2 Master Kush
3 Big Bang
1 Northern Lights
1 White Widow

I simply placed them root tip down into my organic root plugs that came with my cool cab on sunlight sheds. The link is below. Do you think i will be able to produce any seedlings just doing this? I obviously am a noobie and need all the help i can get.

Cool Cab

One of my seeds however when i picked it up the seed shell fell off and all i was left with was the long root tip. I was initially scared and thought that i may of lost the seed and not been able to produce a seedling anymore from it, but i stuck it down in the root plug hole and now i am waiting to see if it will work. I was wondering if anyone knew if I could still produce a seedling if my seed shell fell off b4 i put it in the hole. Thanks. your advice and knowledge is really appreciated.

pretty sure that seed is doomed
your others will work out well for you as you have done exactly as you should have.
germinate the seed to get a nice taproot and pop it into a rapid rooter.
within a few days the plant should emerge from the rooter plug.
if need be you may need to very gently ease the leaves out of the seed casing, but only as a last resort. ie: if it seems the seed casing isnt going to release completly on its own

I have done the same thing to the tap root, actually pulled the seed casting off and damanged the top leaf, it still grew fine! looked funny untill 1st leaf set came in but did fine, yours should be ok. I have heard to be extremely carefull with tap roots but I havent and still no problems. push it into rockwool and it grows. Dwc rules!
