Hey everyone thanks for taking the time to read this. So I'm planning out my grow room and was just wondering. Im plannin on getting this Cooltube hood for 400w hps/mh.(400w Ballast Air Cool Tube MH HPS Grow Light System). I understand you have to also buy an inline fan, so I was thinking about buying this 6" inline fan from Panasonic(FV-30NLF1 - Inline Fans - Shop and Compare at Panasonic). Can I run that hood/fan setup like this and will it be sufficient to expell the heat from the light and keep the room a nice temperature: DIY Carbon Scrubber--->Cooltube with Light---->Fan---->Ducting out Would it be better to have the carbon scrubber at the beginning of the exhaust like shown above, or at the end of the exhaust right before it expells the air into the open? Thanks in advance everyone, gotta love the City!!
