How often and for how long does your exhaust fan run? is it too much if it is running for 30 seconds every 2 minutes?
no, i don't believe there is ever a need to have a "strong," airflow. all that is really needed is a "gentle," breeze throughout the entire plant. you don't need tornado strength air, blowing your plants all over the place. you just want to keep fresh air flowing.k so u dont feel there are any negative side effects of having strong airflow through the tent for 12 hours straight?
Look into "Can Fans" they cost a little more, but are worth it. At the end of June it will be 4 yrs straight for my 6" Hi Output room exhaust fan mounted to carbon filter. My intake & hood exhaust are Cans also. One thing that really help with the lifespan of an inline fan, is to filter the air before it goes through the fan.interesting thread, i have mine on 24/7 too, go through a lot of fans though, anyone know any that are designed for grow rooms that might run at a lower motor speed or something to stop them burning out every few months?
