I am using a cap 6" (value line) now and is kinda loud, just wondering if there was something a little less noisy. (vortex or any other brands i should consider?)
Any Advice on a Quiet Inline Exhaust Fan?

MaxFan is the absolute quietest and moves the most air. They are extremely expensive.
Vortex is also a great fan, quiet and efficient. A little louder than Maxfan & a little less expensive.
You may also want to look into Duct Silencers. Phresh is a good brand. Phat also just came out with one with fiberglass insides rather than foam. Supposed to last alot longer.
Hope this helps.

Eco makes an ellicient fan. Also consider putting your fan on a fan speed control turn it down until it's desirably less noisy and have it hooked up to a thermostat that exhausts when temperatures reach too high.
If it's running constantly than turn the speed up slightly until you hear your fan turn off eventually.
duct mufflers are expensive but they work if it's too hot to silence your fans. About 90 bucks each for a six inch muffler

Can you clairify where the sound is you want reduced?
Is it the sound coming out of the exhaust ducting that is too loud? or the sound in the room that you are growing in? or the humming sound you can hear it other parts of the house you are worried about?
I personally use a CAN Filter 50 with a 6"High Output Can Fan, but with a speed controller dialed to 60%, that way it runs quieter but still provides my small closet with more then enough exhaust CFM plus doubles as it creates negitive pressure for my passive intake

Well the closet is in my bedroom and i can here the fan in other parts of the house. I was thinking about moving the CAP valueline 6 inch fan into the attic that way there is some sort of insulation to dampen the sound. I also ordered a duct silencer from phresh. I should buy a speed controller my closet is 4'w x7'L 8 foot ceileings do you think I could get away with turning down the power Im only running one 1000 wat magnum xxxl and my carbon filter...

Hoagtech`s right, attic is a bad choice if temps get bad in the summer. Could lead to motor failure(my can fan has a thermal sensor that will turn itself off if its too hot) or start a fire.
Dont wory about the silencer unless the actual sound coming out of the exhaust duct with the air is too much noise, I can only feel air and no sound out of my plastic insulated 25ft duct.
Try the speed controller first, then if its still too much, then build a small box with sound insulation foam inside to cover the motor. If still too much then buy CAN FAN!
Dont forget to use foam liners on everything on your shelfing and such to reduce vibrations

Im liking your setup. I never though to put 2x4's on braces above your lights. Its a little edgy though if your fan fails your going to have heat buildup with wood next it.Hoagtech`s right, attic is a bad choice if temps get bad in the summer.

It looks super organized though I'd hate to change it.
A high temp shutdown controller could be a worthy investment for you.
