600W closet AUTO GROW, time is now

Hello everyone, it has been a while since I've been on these forums. Here is my current "planned" setup, I will begin this grow in a month or less, does this set up look OK to you?

Questions:
1. Do I have the right idea by using the flexible washer/dryer ducting to connect the carbon filter, fan, and muffler? or should I directly attach everything. (Like directly attach the scrubber to the light and then directly attach the fan to the other end of the light without any ducting in between.

2. If I leave one of the sliding closet doors cracked for most of each day, will that serve as an intake? and will it effect the efficiency of the carbon filter in any way?

Thanks in advance everyone!

You're gonna have a real tough time keeping temperatures in a good place with such a big light in a closet. If you're willing to put a hole in the door/wall for the fan to push air out, then air will naturally be drawn in and it will help a lot.

Leaving the door open will help with temperatures, but with no forced exhaust you will likely need the door completely open to make enough of a difference.

If the door is open then the carbon filter will not do nearly as much to reduce the smell.

If the only air leaving the room goes through the carbon scrubber it will work very well.

Thanks for the reply,
I am planning on exhausting the room with a 400cfm fan, push it through a muffler, then exhaust it via a hole in the ceiling of the closet. shouldn't that work?
Also, I need the scrubber to work at maximum efficiency, so what could I do instead of cracking the door?
Are you saying if my closet door was cracked an inch or so, that the carbon scrubber won't do its job and there could be a bunch of stink coming from the closet?

The flex in the ducting will reduce power from your fan, so if you run into problems try straight lines.

With an exhaust but no intake it should keep smells under control pretty well, and even without the door cracked air will be pulled in from somewhere.(above/below the doors)

If the doors are opened only a bit to where you can still feel air being sucked in the smell probably wont escape, but the only way to be sure is to use your nose.

You should run the fan strait into the muffler, thats how they work best I believe. Less ducting is always better for efficiency. I agree with sub that cracks around the doors should be enough intake. A smaller intake hole in the door would be ideal but then you go a hole in your door to explain. It's all about negative pressure to keep the smell down/contained. Definitely a big enough fan, might want a speed controller if you don't have one.
