4x4x6.5 ft Grow Tent Air Flow Reassurance

Whats up everyone.

I just need to get some questions answered, I am about 90% sure on my setup.

-Grow Tent 4x4x6.5'ft
--440 CFM inline fan
---6' Alum. Flex duct with clamps 25'ft
----Fan speed controller
-----400W Bat Wing Lamp Hps/Mh Internal Ballast *HOT* ( NOT COOL TUBE )
------12'in Mounted Wall Fan

** tent information

-Tent Left and Right sides: 6'' Air Ducts (cool tube)
--Tent Back: (2) 4" Air Ducts
---Tent Top: (2) 6" Exhaust Ducts
----Tent Bottom: (3) 3"x19" Mesh Air Vents

Okay, Using the inline fan mounted on the roof, I plan on exhausting the air out of one Top 6" Exhaust port.
Leaving the bottom Mesh intake ports open. Should I have more open?

The tent will be placed in an empty bedroom with running A/C no warmer than 77F in the bedroom.

? Will this be the same temp in the grow tent?
? Do i need some intake fans? Or is the wall mounted in the tent sufficient?

Thanks Everyone, Pictures if anyone needs can be uploaded.

Your tent temps will obviously be higher than then ambient temp of the room its in due to your light. Are you venting outside of the room or just venting in same space? Your setup is almost the same as mine. I also use a passive intake for lights off times and during light hours I always have a whole side of the tent unzipped. Your wall fan should be just fine. I have a post in the Nv patient fourms will pics of my setup if you need a visual. Good luck buddy.

Thank you very much for the support, I will take a look at that post you mentioned. Ty again

**Good Question about where I am venting my air.
-I choose to vent the exhaust outside the room into the laundry room, through the door.

I am not to worried about the smell, I forgot to mention I have a c. scrubber.
Leaving the entire tent open sounds like a good idea.

Thanks for the input. The More post the better! Info is Info

With 440CFM you most likely will not need the fan speed controller, I am growing out of a tent with exact dimensions but am using 600W cool tube HPS and 400W bulb/reflector MH and require the fan to run 24/7 when lights are on, during lights off the fan runs for 15 minutes every 2 hours.

My ambient room temps yesterday are about 75 and in the tent it is about 80 when lights were on, now we have had 78+ weather for 3 days now, can't wait next week goes down to into the 55 - 60 range and possibility of flurries!

regards,

Great information Ru4r34l!
I planned on using the low/medium speed during the night cycle. Could be over kill, but can never be over prepared

Please feel free to chime in everyone and anyone! I do not mind questions either

It's quite nice when the weather ducks under after some heat, near the Rockies we can get anything blowing in anytime.

As a plus what would the coming May weekend be without a fireban and rain!
