The exhaust within the grow room is controlled and is only used when temperatures rise to an unsuitable level the humidity is too high or the co2 levels have risen to an unsafe level.
Grow room exhaust to attic.
If your grow room uses a passive intake method you should ensure that the intake hole is bigger than the exhaust hole three or four times to allow for the proper suction of air.
Hold on to this number.
Next we are going to multiply it by the efficiency drop.
Unless there s a lock on the door anybody looking for a bathroom or some paper towels could accidentally stumble into your grow room.
Clip on fans or an oscillating fan is all you need to create a light artificial breeze.
Not as much room to grow.
Another problem with growing in closets is that there is no ventilation.
Just use a ducting till the window door attic chimney to take the exhaust air out through these openings.
A smart inline duct fan designed to quietly ventilate hydroponic grow rooms boost heating cooling to rooms circulate fresh air exhaust projects and cool av closets.
Exhaust air is pretty much hot and they are most likely to stay stuck to the roof of the room.
Probably but that doesn t stop us trying.
Some growers using a closed loop co2 enriched room will run their exhaust fan for 10 15 minutes every couple of hours to ensure their environment never gets stale.
This is the cubic feet measurement of your room.
Unless or until you re draining them out with an active exhaust for the grow tent ventilation system it will be going to ruin up the whole plan.
The dimensions of your grow room or tent.
Outside ducting will need to connect to a vent or window to exhaust hot air from the grow tent.
However the space directly beneath.
Inside the grow tent it is also important to maintain good airflow.
Featuring an inline mixed flow design the duct fan can maintain airflow even in high static pressure applications.
You may as well opt to install more than one passive intake hole to increase the amount of air flowing into the grow room.
This is why a very out of the way closet is preferable.
