If your house has conditioned air, you might be able to draw off of that to cool your cabinet in the attic. A small cabinet can be cooled by a 4" line and a real exhaust fan. Install a bathroom fan style ceiling grate in an out of the way place (spare bedroom closet?) and no one will know what's up there. Just, uhh, don't pull from the bathroom... Not only would you suck bathroom smells into the tent, but if your bathroom fan is powerful enough and the door is shut, it could conceivably pull air from the tent into the bathroom 😬
Look for a fan that can do in the neighbourhood of 200cfm, preferably with a speed controller. I have this Vivosun one: https://www.amazon.ca/dp/B01DXYMGOM but if you're not on a budget, this one would be excellent: https://www.amazon.ca/gp/aw/d/B06ZXWN3BG
Avoid the super cheap "booster" fans, they're only useful as an add-on in the middle of a long run.
If you aren’t planning on getting a bigger tent I would stick with a 4” exhaust and a 4”/6” carbon filter. Here’s the link for the fan and one for the filter . I use a bigger fan and filter personally, but that’s because I plan on getting a bigger tent after my third or fourth grow. Based on the dimensions of your tent this should be a solid setup for you even if you go up a bit in the future.
I'm currently using their inline fan (VIVOSUN 4 Inch 190 CFM Inline Duct Fan with Variable Speed Controller for Ventilation https://www.amazon.ca/dp/B01DXYMGOM/ref=cm_sw_r_cp_apa_i_5ihjDb9NQHYHD)
Anyone know if this is something I should replace too? Still under return period.
So I made this thread recently about a clone I bought on 4/20/19.

Now, a bit of time has passed and it's grown a bit more, but unfortunately still under very inadequate lighting. The temp and humidity were wrong this entire time, but I seem to have stabilized that. I plan on ordering this grow tent, just ordered this LED light, and am looking at this (or this) in combination with this to bring it all together. Anyone see any reason why this wouldn't be enough?
Here is a pic of my setup
The filter and in line Fan I use together cost about $100. To connect it I 3d printed this part and super glued it to the back vent and put some sealer on. You could just buy a connecter tho.
Altogether about $600
$450 for the printer
$100 for the filter
And those minis only cost $20-30 in resin to print.I’ve printed other stuff som I’m not exactly sure.
And a bulk IPA pack for $20
This isn’t necessary but I also got an Ultrasonic cleaner for cleaning the prints when they are done.
