Alright first let me say i can normally take better pics however i dropped my phone on a roof this morning, needless to say the only thing truly effected was the camera.... Yes im furious. Now let break this down from the start. The first picture will be the intake fan for the LIGHT, i normally keep it in a box for debris control. It starts outside of tent runs inside through top side hole and into cooling hood.
The next set of pics will show you the exhaust from cooling hood out of tent. Comes out through the top of tent.
Next is my outtake with the carbon filter. Some allow for the filter to mount directly to fan, mine did not. So i used 6in ducting to connect. You keep the outake at the top simply because thats where all your heat goes (heat rises). Like i mentioned before i got lucky with an old wood stove chimney that was fitted for 6in ducting, so i was able to get the heat out of the room very well.
And finally my tent intake which is at my bottom left port. Like mentioned before i set the ducting for my intake on the floor because thats where my coldest air is. As of right now it looks pretty rough with all my zipties on it for my ratchet straps but it works likes a charm!
Sorry theres no lights on either its currently my dark period so the only light was from my phone flash. Hate going near them while they sleep, dont want to disturb them lol. Hopefully this helps a little more. I had to play with my fans and lights for 3 days before i got my airflow correct and i still need to add one more small clip on fan for in tent circulation.
