First Time Grower, Germinated Yet???

Hey Guys, I just ordered some seeds from
http://www.marijuana-seeds-canada.com

5 fem blue mystic
5 fem white castle
and just for the heck of it and for a little extra girth 4 random gender BC Big Bud

Any who this is my first time growing, I ve watched Mr Green and Jortes Cervantes 20x each and I'm pretty decked out I think

I live in Atlantic Canada and the weather has been getting colder, I went out to the mail box 8 business days after ordering and there was my "DVD"
I was so worried the cold killed them, I dropped them all in water, they all floated for a while and then all sank apart from one( Ive since heard floating or sinking makes no difference)
Anyway its been about 36 hours and I THINK they are ALIVE!!!! Unless I've slipped into a hopeless dilerium I believe I see some white protuberances.

I thought Id get the experts at rollitup gimmie a second opinion.

This pic is of the Big bud seeds(which are fucking huge compared to the other strains hence the name I guess)
The others look similar in that i think they are cracking.
The top left seed has what i believe to be a white root, Is it? Can I plant it now or should it be really opened up.
I dont have a real frame of reference, so is a "cracked" seed open a little with a tiny root or is it like totally blown open. In other words is it open enough to plant now or should i wait till its really Bursting
I did hear somewhere that open too much = not good

Any advice would be sweet
Peace all


P.S. the pic is kinda shitty, blame it on the cell phone

They look like they germed, if so you need to get them out of the water now, too much water will drown it.
