How much do duct reducers effect airflow? Specifically a 6 inch 400cfm inline fan with a 6"-4" reducer? Asking because tent hole is smaller than my fan and hood.

Anyone know exactly how much reducers effect your air flow?

I just got in a new grow tent and after setting it up i realized that the exhaust hole in the tent are ~5in and my hood and fan are both 6 inches. I have a 6"-4" reducer for the ducts but I am wondering how much this will restrict my airflow? Any suggestions on how to get around this problem?

I have a 400w HPS in a 4x4x8 grow tent, where would 400 cfm put me?

Why do you say that?

Thats a very good deal, thanks.

I see these stanley blower fans in walmart pretty cheap: I was curious if anyone has been able to make them work as an exhaust fan alternative? Is there a good way to connect ducts to these? How do they compare with other exhaust fans? Thinking about picking one up but not sure.

Where can you find it in HD/Lowes?

What form of citric acid? I used lemon juice when I ran out of ph down once and it fermented in my res:dunce:. Thanks for the advice guys

Just ordered a 4x4x7 tent and will have a 400w hps in it. I was curious if anyone could tell me roughly how much ventilation I will need. With what I currently have I can generate ~250 cfm of exhaust and have some 4inch fans for intake. Will this be enough? Never used a tent before so not...

I didn't see a 25 dollar bong

Thanks, very nice stuff but I am looking for prices lower than that. My local shops which have very high quality glass around the same prices. I am just curious if there is a site that sells nice stuff at very low prices.
