Temperature Experience with Cooltubes Vs. XXXL Magnum Reflectors

I have a 8x4 tent with 1 Magnum XXXL relflector with a 6" fan (440cfm) sucking out the the air, but I also have a 8" fan(747cfm) sucking out of a 80 pound 46" carbon filter blowing into the XXXL. It is vented out of a window that is about 6 feet away and there are no bends in flexible ducting. My temps are at a constant 77.5f when the lights are on. I also have a 6x6 tent with a 6" cooltube and a 6" fan with 6" carbon filter. This tent is on the other side of the room and there is like 20 feet of ducting with alot of bends in the ducting to the window. Now my 6x6 tent is always alot cooler 73f-75f. I am running 1000w on both tents.

I just setup another 8x4 tent. I have an extra xxxl magnum reflector but I am wondering it I just go get 2 cooltubes to run 2 1000w lights could I maintain a 75f temperature. The vent ducting would not be no longer than 4.5 feet from the window. This setup is in the basement

hey there i cant anser your quastion but i do have one for you! lol
im planning to get a Magnum XXXL- Air-Cooled Reflector for my 600 watts hps this is gena be in my tent which is 1.2m x 1.2m x 2m tall,

I have 1 1000w in a xxxl magnum temps are constant at 78f. A 600w watt would be good. I have it vented out a basement window

nice one. cant wait to get my magnum, i should have it by time its time for flowering my babys,

I do a 5.5w x 8.2 L and a 6.6 height. I run two cooltubes with 1000 watt digitals. My intake for the lights in on one end and the other end is the outtake. The outtake has an 8 inch inline on a rheostat that is going into a poly tent around the window and then blowing threw the blinds. I have a back up 6 inch inline on a humidistat.. I set it to 60.
My temps stay at 27. When i run c02 i use an a/c to shut off my tent outake to keep the co2 and cool air trapped. The hottest it gets is 29c. My a/c is 11000 btus and its ran on low unless the temps outside are over 29c.
I think humidity is a problem in small spaces.
When the lights turn off the outtake kicks on and does its job dehuming. The a/c is to make sure its cool and dry in the tent and avoid the outakes settings. You want that outtake off in the day time but on at night.
When it gets cold i just turn the 8 inch fan on low to produce more heat in the tent.
In the winter avoid using the outtake fan when your lights first go off. That way you keep the hot air inside the tent.
hope this helps
