Exhaust fan off at night?

Hey guys,

Quick question about the ventilation at night in my tent.

Its a small 80cm x 80cm x 180cm tent and I only have 1 seedling in there at the moment under an LED waiting to sprout.

My question is at night time the ambient temperature sits around 21c-24c (70f-75f), so would it be ok for me to leave the extraction fan off for the 6 hours that the light is off? (6" oscillating fan will be on and passive intakes will still be open)

Maybe have it on for 10 minutes every hour or something?

If this is ok, would it be ok to do this for the first 3 weeks or so while there is no smell coming from the plant?

The noise of the extractor fan can be slightly annoying while trying to sleep right next to it so would be nice if i could turn it off during the dark period and knowing my plant will be fine. (Ill have it on a timer to come back on in the morning)

All all help/advice would be appreciated.

Thanks!

Sure but like you intend, keep a fan on

just to blow away any 02 around the leaf stomata

I do stress a gentle breeze is ideal as too much will chill the plant

good luck

I'd say it's ok until she gets into flowering.

I find mold comes over buds easy and fast in late flower, especially if the exhaust is off. The plants seem to drink more and transpire more, so when the exhaust fan is off all that humidity just sits in the room.

I'd say as long as humidity doesn't creep much over 50% it'd be ok all the way through. Mine was around 65% lights off with the exhaust running at night in a 2x4x5' tent and I had a little problem with mold on the bigger buds.
