I have a 8x6 space that I want to grow in in my attic. It is also 7 feet tall. This will be my 2nd grow. I'm only planning on using 7x5 space because I want to be able to move around in the space i am growing. I have one BIG criteria that I have though when setting up my room, NO NOISE AT ALL. By that, I mean no huge blower fans, inline fans, loud ballasts, etc. I may be able to run a small fan on a low setting but that's about as much noise as I can have. I've already got the space light proofed. To get to the point, I was wondering if this 400 watt HPS would do the job? http://cgi.ebay.com/DIGITAL-GROW-LIG...cmdZV iewItem

Does anyone have any experience w/ the digital ballasts? Do they really save money, run super quiet, produce less heat, and run more efficiently overall? Is it worth the extra money?

Also, the current temperature without the HPS light is 66 degrees. Will it get too hot when I put a 400 watt HPS light there? Remember, I cannot run any exhaust or intake fans with my setup due to noise restrictions and budget. Thanks for reading my long ass complicated situation I have for you guys. Thanks in advance for all the help!
