Blue 47 from seed

Hey everyone,
This is my first for everything on this site, I gotta say i've been a member for a while and have just been reading, and I have learned so much!
So I made myself a small grow box
inside dimensions- 15"x15"x4'
lined with mylar, two computer fans entrance air, one computer fan exhaust.
LED light mixed blue and red(ebay $60 good buy) I have a small hydroponic system set up with a 2 or 3gal bucket and drip system.

I am growing Blue 47 a cross between AK47 and Blueberry 60%indica/40%sativa
needless to say i'm very excited about my first grow.

I started the seed three days ago with no problems and then went into the rockwool cube under a dome, and there she stays for a little while anyways she is on half strength nutes(DNF 2part)

Any advice would be great as well as comments
Later dudes

Very nice. Where did you get the seeds from? Looks like an awesome setup. One thing I'd comment on would be maybe no lights while it's sprouting. I'm not 100% sure about that though because I just did pretty much the same thing with my aerogarden but I thought light hurts the roots. Very nice setup man very well planned out. I'm new here too but I've read a lot and I wish you a good grow and I'll subscribe.
