Fan controller stops at night? What about smell

[DrGreen]

Fan controller stops at night as temps drop to 20 , how do I manage smell as there periods of no neg pressure
Its set minimum at 40% I thought it would idle there not stop
Could this be cause my 4inch is so small it stops wen slows, or is this normal ?

4 inch It's that small , 40% of small = tiny and that's how much air is sucking out , so need to keep her on full 24 hours buddy 😜👍

What controller are you using mate?
Should be possible to set your controller to lower the speed of the extraction fan when it drops down to 20 degrees.

Yeah was too cold at night 12degrees and 23 in the day so got this and it solved my problems to 21degree nights but I noticed its so slow its I presume stopped coz no sound or feel air going in lol
Max day temps 28 as controllers set there perfec

Was getting a 6 inch to replace it I take it wit controllerr I can go bigger but won't nights be same? Or will 40% on A bigger fan be noticed more then a 4 inch

Dr green from what I understand is your best keep ur fans on 24/7 ...intake and outake..obviously need to be on a constant power supply unlike ur lights which are timed..I'm a newbie so still learning myself. .on second grow myself. .good luck. ..

[the jakal]

you dont need the intake on when light go off, you should be able to set your extraction to just slow down and not go off completely.

sometimes you have to mess about adjusting the settings a bit by bit to get it right

have your intake set to come on with your lights

[DrGreen]

dont use intake passive is enough :P

Hope all is working out. Your plants are beautiful
