day 2 seed cracked

i finally got my 6x4 room set up
i have two hydroponic drip irrigation system
one is the 8 set water farm
and the other system is just smalller
i also have a 8 inch vortex fan and i am going to add a carboon filter on it

i have 1 1000 watt hps and 1 400w mh
mh is for veg and hps for flowering

i started germenating 10 seeds yesterday with paper towel and today i looked and 3 cracked alrdy .
this is my first grow
it is going to be blueberry x northern lights. hopefully
iam just worried my lamps might get to hot..
but i have fans.

once more seeds crack i am going to put it in rockwool and then water it 3 times a day
and 18/6 with 400w mh

any comments?

thx.

sorrie not 8 inch vortex i mean 6 inch

sounds like a good setup to me. im germinating my seeds right now for my first grow too, but im using soil to start with. im also worried about temp but i have 2 computer fans one blowing in one sucking air out and i can always add another fan it it gets too hot. keep this updated i wanna see how things turn out for u
