bieng that they are so small, a rockwool cube maybe? if you plan on growing all the way through harvest in the aerogarden, you'll want some more cfl's another 3-4 should do the trick. get the 6500k ones for veg and 3000k for flower. use both but maybe do 4 of one type and 2 of the other, then switch when you go to flowering...
it might be the other way around for the temps, i'd suggest some more reading.
