Fan Speed Help

Hello,

Setup:

I have a 3x3x7 Gorillia Grow Tent - this is 63CF. have a 193CF fan (4") off the ceiling of the tent going into a Phresh Carbon Filter and then goes directly outside into a dryer vent. (straight shot, less than 2feet away) There is a speedster dial on the fan (ie: LOW to MEDIUM to HIGH)

My Thoughts:

I am guessing that HIGH is overkill and not something I should do? I am guessing that I should keep it at MEDIUM.

Specific Questions:
1. Is there any advantage to running it LOWER or HIGHER?

2. Should I run it higher during Lights On (HOTTER) and lower when Lights Out (Cooler)?

3. If I run it too high when lights out, does that take too much CO2 out of the tent and not good?

Thank you very much / Peace!

1 try to use it as low as you can to maintain temps, negative pressure, and do a better job of removing odors.

2. You can, I have, depends on how high you have to run during lights on.

3. Are you running co2? You don’t use co2 at night as far as I know, Either way c02 needs a sealed room

I run my fan on low. If I do not it completely sucks out any moisture in my room. I would keep it as low as possible where temps and humidity are just right during lights on, then when the lights are off it should provide the same good environment.
