First of all I just wana say great looking plants man, they look like the result of alot of hard work and effort so I hope they as good as you hope.


Also you've kind of solved alot of headache for me too because I was planning for along time on sucking air out through the lights/top of the roof into the carbon filter.Very inefficient now I see your setup. Having the carbon sucked out directly into the growing environment to neutralise instead of having the environment sucked into the carbon filter makes much more sense.

Also I got a few questions regarding your equiptment. I recently bought that exact fan and its causing alot of problems for me. Its noisy as fuck basically, how do you tackle that problem? The ducting dosen't even look insulated, so the airflow must be noisy, also, isn't it dangerous to have it hanging at a 90 degree angle? And also if your taking the carbon through the lights and out of the room, how does the stale air in the room actually room get removed? Sorry for the noob questions.
