Venting at Lights off?

Hi,

Just a quick question, a little lost

The climate is cold around here, and when I mean cold, I mean I have to put a 60W Tubular Heater plugged into a thermostat to keep the temp at lights out above 20c (around 68F). When I check the temp in the morning, min is bang on 20C .

Currently using a RVK Fan to vent with passive intake, set to come on when the lights comes on, and off when the lights goes off. (My thinkin behind this, is that it does get cold once the lights are off, and if I keep the fan on, then there are no point of using the heater, as the warmed air would get sucked out immediately, and the ladies might get stress due to the cold.

Am I doing something wrong here, does everyone, leave the fan on running 24/7 (apart when dosing CO2)?

My ladies have just started to flower, and I am worried ! I dont want to cause them budrot or mold due to me being a dumb ass and not switching on the fan during lights off when I am suppose to! Humidity is around 50-60% Min-Max.

I also have a Osilating(spelling) fan, inside the growbox, on 24/7 giving some constant air movement inside, is this enough?

Please could somebody shed some light on this matter,

Thx a million

When the lights go off during flowering, ya want the temps not to change much. If ya have to ya can put a heater in there when lights go off.

What I am asking is should the RVK fan be on during lights off, to give the constant intake of fresh air?

If the RVK fan is off during lights out, Is a Oscilaing fan be sufficent to aviod budrot, and mould?

Leave the fans on. Fresh air is good. If the temps are messed up with it on then adjust the fan so maybe on half the time.

Thx for the advice Dirtyboy, have set the fan to be on 24/7 for now, and keeping an eye on the min temp, and will try to adjust accordingly.
