Sizing my box for 2 plants???

right now i have a 1.5' x 1.5' box and want to get two plants. Should I make a new box 1' x 2'?? I 'm gonna use the same box all the way through the grow.

I have 2 T5 HO daylight mounted verticle on the opposite walls puttin out 5k lumens a piece and two 23 watt soft white hanging over the top puttin out 1600 lumens a piece. Heard good things about using whole spectrum.

I'm gonna swith the daylights in the T5 to soft white and put daylight bulbs in the top where the soft white were.

What do you think??????????

Plus have a 5" computer fan blowing fresh air in @ the bottom and 4" computer fan for the exaust at the top opposite sides.

What kind of results should i expect I dont know the strand pf the seeds and know some strand are bussire than others. I read somewhere 1 sq ft for each plant but is that right.. What have you found in your experience???
