I've got a Growlab GL120, 4 x 4 x 6.5 tent, a Lumitek electronic 600watt ballast, switchable to 400, with a "super lumens" setting...whatever that is...it's now running a Sunmaster grow lamp, which I will switch to a Solarmax for flowering. The reflector is a Sun System yield master 2.
I am using Fox Farm soil in 3 gallon pots, water is at 6.5 ph, seeds are in. Light is set at 400W (will switch to 600 in a week or two), on an 18/6 cycle.
I wasn't planning on any additional nutrients until flowering, and will need suggestions at that time.
I am adding a 4" Vortex inline fan tomorrow, and a 4 x 12 Phresh Filter will be added to that once I need the odor control. I will also be adding a small clip on fan to move air around the tent.
The tent is much bigger than I thought it would be - I should have measured out 4 x 4!
The back row and two of the middle row are vanilla kush second row on the right is a rocklock, then the front row are kandy kush, pineapple express and exile.
I have raised the light up about a foot and adjusted the cord from the light since taking the pic.

Through the tents viewing windows...

Any suggestions/tips about any of this would be appreciated, comments about the specific strains, and if I'm doing something wrong or stupid please feel free to point it out.
