    I spotted this today and it got me thinking, I could easily ramp it up to say, 300watts, for about $150. It's passive cooled so there is no noise, and even I could build it... but what do you think of using white LED's? Would it work?

    I think it will work, if you buy warm white leds. Cool white doesn't work.

    The cool white would work well for vegging wouldn't it?

    No, actualy not. The light spectrum of a typical CW led does have lot's of blue, but lacks were is the maximum action spectra of plants, witch is in red band.

    The WW led have a good amount of blue and have a excellent peak in a wide red band. Those lamps have a more balanced light spectrum than CW leds.

    If I would you, I'd use only WW leds for entire grow. :D
