How long does aeroponics take

So if I had an aeroponics system about 16 plants in a 4x4 area with a 400 watt hps. Running the pump on 1 minute and off 4 minutes. If i start from seed with a kush plant how much time could I expect it to grow from the day of germination to the day I manicure and start drying?

Veg stage for 3 week then flower for 8 weeks =Total 11 weeks

hours and hours...

Not long...

Basic System ... 400W MH.
And remember, this is my first attempt with aero and is more a trial than anything else so no major care has been taken lol
1 Week (7 days) growth:
