Hey Medi,
Why don't you just run your fans all the time?
Does it get really cold during the dark cycle?
That way you won't need the Ductstat and you can save yourself a dollar or 30.
You could then buy a digital temp/ humidity gauge.
I have air circulating through my cab' 24hrs a day but it doesn't get to cold ever where I live.
I just run my fans in the day times because that is when it gets really hot.
At night it would be a good temperature but i purposely open up my window to let it get cold -like even when its freezing outside,but most nights are like 50 degrees f .I think it helps air out the room and i think it gives me a higher possibility of getting purple- purple kush lol
So i think im just going to get a digital temp/ humidity gauge i think there only like 15$ and probably forget about the ductstat and then add one more small fan at the bottom where i will put a hole for it to intake air from outside and ill put a hole at the top for it to blow hot air out and ill just have the fans on for the whole light cycle!
Oh yeah and i still have spider mites ,not to bad or too many .
Ive been waiting a couple days to spray again so im not dousing my plants all the time with poisoin so tongiht at lights off im going to spray again.
