130CMH is 76CFM. So if the intake is 76CFM and the exhaust is 115CFM then it should be fine. Carbon filters and lots of ducting can slow air flow. So if you have a lot of ducting you might need a more powerful exhaust fan.
smoketoker Reviewed by smoketoker on . New Grow Room Advice Hey Guys, I am planning my first real grow room setup. I would like to run things past you guys who are a lot more experienced and can guide me better. So, let me start by explaining what I have, and want :-) Basically, I just want to be self sufficient.. I smoke ~ 2 - 3 oz a month. I have seen these autoflowering strains which allow seed - bud in 8 - 10 weeks, great! I can grow a handful of different strains, for 2 months and get enough to keep me going until the next crop. Or so Rating: 5
