Gudday all,
I second that, welcome to aero power, and yeah aerobuds is right, dump those ladies down to 12/12 of they will grow to the roof. I use an aeroflo 60 with 2400 watta over it, you can get in excess of 5 inches growth per day....its often the case for me that its too much growth, as I am a SOG grower.
I could tell you a hilarious story about my attempts at growing Nevilles Haze in my areroflo unit, but I'd only embarass myself

I flowered them at 6inches, they got to over 7 foot high in the unit...godawful nightmare but explosive growth.
Regds,
