I dig the way you run the airflow from veg to flower. Killing 2 birds one stoneI have a 3 wall to outside grow room. One wall touching the house. I run intake from my basement through the wall and into the flower rooms main room. My veg tent exhausts to the flower room and I intake from the flower room. (I do this to increase veg tent temps as they want it hotter and more humid. 8” exhaust fan blowing to the outside. That’s my flow.
8” fan sits right above the tent exhaust fan outlet.
If you want perfect negative pressure:
-run your exhaust fan one size bigger than fresh air intake. So 8” exhaust 6” intake. And run them at the same fan speed setting.
For me, if I control basement temps to stay low, I can control room temps with the fans. Humidity dump at night, cold dump (make room colder than the night temps), drop temps during the day with an environment dump from exhaust.
thank you sir.I dig the way you run the airflow from veg to flower. Killing 2 birds one stone
As do I, I actually took the vent out, and added about 8ft of flex duct so its output is right behind my 16in shop fan (circulation on a speed controller) great minds. If something ain’t quite doing it, make it. In times I don’t need it, I scrunch it back up to the ceiling and tape it. Toss this your homies way.Smaller the room the harder the control as well. I have a buddy with a 4x6 room and his LED lights alone push 80 degrees at 50% intensity. He is forced to run direct AC vent from central air to keep temps low.
thank you sir.
Such a bonus.So I do Not use an AC unit, I use my basement for all cold/cooling.
i wondering what im doing wrong then i have a 4x4x7 tent with a 6 inch spider farmer exhaust fan blowing air out and and a 8 inch ac infinity booster fan blowing air into the tent and your not gonna run both fo them on the same levels and have it work lolI have a 3 wall to outside grow room.
