Is my filter too strong?

Good question, I would like to know as well!

the filter is rated for higher CFM, so I don't think will be too much of an issue.

You should be perfectly fine. If your gonna start running co2, you won't want to cycle the fan on when its running. Otherwise you'll be fine, the exchange will be giving you fresh co2 from the fresh air.
No offence, but its like thing that putting your plants outside in all that fresh air will be a bad thing... Hehehe

Lol no offense taken
. i was thinking more along the lines of it won't be able to take in as much CO2 because the air is filtering to quickly.

Not trying to be a dick, but I think it's funny when people start a new thread for some feedback, then answer themselves... The more circulation the better!

Lol, I posted that in response to him saying my filter would wear out quickly, but yes I do tend to answer a lot of my own questions, but it takes me asking the question first to produce an answer. Secondly, I'm not your average take an answer and follow that method to the T, I ask others just for simple input. Whether it be negative or positive. I'm completely open to criticism and will never take offense to anything. So don't worry about "feeling like a dick" it's all good my friend.

the best thing for your plants are moving leaves, so make sure you throw a fan in there. that way as the air exchanges, the oxygen that's being expelled from the leaves will move from the area and allow the new air that's coming in to replace this fresh air that has ~350ppm of co2. Also the added benefit of strengthening the stems.

A filter generally reduces efficiency by around 15-20%. So a 440 would lose approx 44CFM by adding a filter into the fan.
As long as duct runs are straight and there are no crazy angles in the ducting then up to around 10ft of ducting will reduce efficiency a little again by about 10%
If you've got 2x90degree bends in your ducting for example each 90 restricts another 20% air flow.
So a few bends and a filter and you could be down near 300CFM but not from a filter alone.
