more than 400 watts for one plant

I currently have an AMS (1) plant growing inside my closest. I am using an aerogarden that was discarded by my mother, and besides the stock light in the aero i also have a 400 HPS, as well as 225 watts of compact fluorescents. Im really confused which light should i stick with? any tips would be appreciated.

Its up to you..

CFLs are proving themselves, but HID is the solid tried and tested technoligy ...

if heat isn't an issue and you have adequate ventilation then I'd go the 400, but if you're not able to ventilate well - i.e just a computer fan or something similar, then go with CFLs.

You can flower and flower well with HPS, but what spectrum are the CFLs you have?

use the 400 and keep it as close as you can
