Is the air going through the filter, then fan, then out of the tent?
Looking awsome!
Just a little FYI, if you don’t already know, your exhaust fan and filter will do you better at the top of your tent.
Keep up the good work! 
No i haven’t had to use the exhaust filter so it’s only taking air in i also have a small fan in the right front corner not shown
Yeah i haven’t had to run the exhaust fan much . The tent actually keeps the odor in quite well
Air exchange is about bringing in the atmospheric gases necessary for photosynthesis, not just heat and humidity control.
I’m trying to understand the setup, because typically one would pull hot air out of the upper volume of the tent, not the lower part. If your climate is different and your challenge is keeping the tent warm, it makes sense to pull cold air from the bottom. Looking at the photo had me scratching my head.
The tent stays at a perfect temp . I have another small fan in the bottom right front moving air around as well as another intake fan in the top left . gauges say all systems go perfect humidity and temp
