Air Extraction setup for co2 systems / lights

Hi all,

 

Does anyone have any guidance on setting up extraction for rooms with co2?

 

One of the things I'm looking at with my new 1.5x3m setup, is running un-filtered extraction through the cool hoods so I can have a lower extraction flow rate of my environment.

 

I currently have a 5" 380m3/hr fan which has done well to keep up with the temps of my 1000w HPS. This runs through a 6" carbon filter and 6" ducting. I've built a foam and wooden box around it and surprisingly been able to reduced the noise of it from 63dB to 54dB while at 100% and from 54dB to 38dB while at 50% power.

 

I'm looking to add another light, so I was thinking to change my cooling fan to an 8" 700 m3/hr and use the 5" for environment only. This would allow for a sealed yet small vacuum situation for co2. But if times get hot, I can have them both pulling air and can turn the co2 off.
