Ben's last questions about exhausting

so Ben has a grow space of 2.7' X 2.7' X 5.25'. it is a Secret Jardin dr80 tent

Ben wanted to buy this fan / filter combo, but had some questions.

Q1: 170 cfm for such a small tent size seems like too much right? is too much negative pressure ok?

* Ben is going with T5 floros all the way through. only growing for personal use so no HPS needed for Ben

Q2: is this the right fan for Ben's small tent? anyone have anything to recommend? Ben will pay more if the quality is much, much greater

If ben used a fake name and linked his account to an email with a fake name he wouldn't have to be annoying and talk in the 3rd person all the time.

As for your question, no there's no such thing as too much air flow. Unless you have enough airflow to literally rip the leaves or vacuum trichromes off of your plants you're fine.

Honestly though, for 170cfm that price is a rip off. You can get more air circulation hooking up a couple of 120mm PC fans for about $30 with shipping and get equivalent air flow and it'll be alot quieter.
