Help me choose a light!!!

[davidhseo]

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!

thats a big space for a low budget. A 400 watt hps is good for 2x2 ft. also temps will vary a lot in an attic. does this attic have vents???? I would build a big cabinet and go with shitloads of 4 ft flouros. and maybe have 3 boxes ...... one mother box, one clone box and one flower box. use small quiet fans

you can get a good harvest from 4 ft flouros if you sog it

Dude, you could live in the South Pole, but if you don't exchange the air in your grow room, the temperatures will soar until it's like a very nice crispy oven.
As to intake fans, I see your noise situation, but if you don't give those plants fresh air, they're going to be strapped for life. You need FRESH air... even if it's a passive intake.

If you want little noise/no-noise, what you can do is buy a big mofo fan... like a Dayton 465 or something... then, run it much slower... it won't produce nearly as much noise.
Maybe you can design a passive intake/exhaust... intake: tube connected to outside on the lowest part of the attic. Exhaust, tube connected to the outside on the highest part of the attic. Still, I think you should get a fan.

Best,
