That how i size it yes that will keep tent in neg pressure
Speed controls on both also help give you a little more control
Exhaust from top and draw fresh air from bottom
Go with a 4 inch intake that runs 150-200 cfm you should be fine
I had 4 of those light fixtures in a 4x4 tent
Alrighty then. I’ll let you know when I get this all set up then. Enjoy your day, dood! Burn one for meh! 
Doing that now lol
Have a great day brother
@garrigan62 why’d you edit the preview? Just curious in case I made a goof or something 
@Countryboyjvd1971 @garrigan62 @dbrn32 @Aolelon After redoing the exhaust and opening the other socks for passive flow until I get the inlet fan this weekend, the temp is perfect. So I thought I’d post a couple one week photos for you guys so you see how good she’s looking.
Next step is learning how to add nutes and memorize the grow bible now that I can relax a little finally.
You’re rent looks exactly like mine except mine is 48x36x5’ it’s a great tent. Looks like a good start!
Its an ipower. Seems to do the job so far
