Exhaust in and Temperatures.

**jamieprov** · 04-11-21, 08:53 PM

I should be okay to turn my exhaust in off to boost temperatures up as the temps outside are getting colder now. The exhaust out will still be pulling fresh air in anyway.
Getting 17c when lights off.
24c when lights on.
Got a heater on as well and still that cold.
I got lights on a cooltube system and its too late to change now.

Not really a question but... yes.

Can you raise the temp in the room that you are getting your air intake from?

Passive intake, yeh dude that's fine but you will still be pulling in cold air.
What heater are you using?
Can you get it near the air intake see if you can pre warm your air coming in?

Heater near your intake and also having it passive might solve your problem

Turning off the intake fan isn't going to hurt.

As funkydawg said, cold air from outside will be coming in anyway. Without the inlet fan, it'll spend a bit more time in there and should be a little warmer.

The colder it gets, the slower the growth. Although the plants have to get really bloody cold before they stop growing at all. Slow growth is still growth, I've had plenty of decent harvests with room temps of <16'C.
