exhaust

Hey everybody, What do you think? Should the intake for air cooled lights be filtered? Not the intake for the grow room itself, only air that is cooling the reflectors. If so, would a bug screen be sufficient or is a more heavy duty filter like Phresh or HEPA needed?

so this could and probably is a stupid question but I have to ask because I'm over thinking it. If you have your inline and hood set up so that it is fan+ducting+hood+ducting+carbon filter. How is going to pull all the air through the carbon filter. Will air not be sucked through the...

just wanted to share my new DIY carbon filter as seen in https://www.rollitup.org/t/the-best-diy-ez-walmart-carbon-filter-for-micro-grows-zen-style.101248 I'm using a 100CFM 12w VenTech inside my humble 1.5'x1.5'x4' and It's working as fine as expected! (:
