I have a little issue on my hand let me explain;
![Confused :confused: :confused:](/styles/smilies/confused.png)
I have a 4 inch 200 cfm inline fan connected to a ducting only on top of grow tent to exhaust hot air out (no filter yet its veg time)

In the bottom I have a ducting fan (100cfm supposedly) but this thing is weaker than a computer fan

Now my question is should I order a 6 inch 400 cfm with a speed controller to exhaust on top of the tent and put the 4 inch 200 cfm to pull fresh air in and get rid of the duct fan

My temps with the current set up is about 27 degrees which is in normal range but for flowering I need lower temps and I will be adding a second mars hydro 600 watts led
For flowering.
So should i keep it this way or change?
And if i go with the 400&200cfm set up I think it will be way too loud for my neighbors
Im stuck what can I do helppppp!!!!
