Hello Guys,

I've always beena 400w man with 4 inch exhaust. Been wanting to upgrade and now have.

I've just got my 6 inch exhaust fan set so i will be upgrading to a 600w happy days.

However i'm thinking from listening to the fan it going to be a bit too loud to run at night towards the end of flowering when i like to leave it on.

Now i grow in a tent and the humidity sky rockets without extraction as i've learned with the dreaded bud rot.

So i can't run the 6 inch exhaust due to noise but i'm think of running the de-humidifier and a small fan inside the tent just for the 12 hours of lights out.

Will this be ok...'' Can't wait to set this 6 inch up tomorrow and put a 600w lamp in there to compliment it! Happy happy happy! :blsmoke:

I know that certain fans can be really loud, I think if you spend a little more $$ you could get one that would do work without all that ruckus, you could also insulate / put foam around the fan to absorb the vibrations, 50% of the noise is probably the vibration not the motor / air movement itself

I recently switched to 6" insulated ducting for the exhaust from my cab. This switch has greatly reduced the noise created by fast moving air. You can now hear how quiet the fan actually is.

The fan on my elec ballast now makes more noise than the exhaust from the cab itself!

how about running the 4 inch fan you are used to and adding the 6 in on a thermostat so it will only kick on when needed? my guess is if the 4 in fan worked for a 400 watt light, the bigger fan will only need to run occasionally.
