400w hps/mh closet grow. Second grow, first indoor.

Hello all I'm aproximately a month into my first indoor grow. After my first outdoor grow this past summer, it clicked that I have a near perfect spot in my upstairs bedroom/attic to get a year round project started. Thanks to all of your very useful information from other threads/posts I had about as sucessful of a grow as a first time newbie using bagseed would. So I figured in order for this to be a better learning experience I can use some of your opinions and input on things, but dont worry! no stupid half assed questions here.

My indoor setup is a larger walk in closet (Will be posting pics tonite)

-400w hps/mh ballast eye hortilux lamps
-walls flat white, doors styrofoamed
-3 exhaust fans, 1 intake, 1 oscilating
-humidifier
-homemade co2 setup (Which suprisingly is working great!)

I'm gona be posting my nute solution for veg and flower tonight when i post pics.


Happy Thanksgiving!
