While he's not really wrong a better way to run it with our cheap sensors would be to have multiple one at canopy that can still give accurate night temps and humidity one shaded from light for lights on and use a ir temp gun for plant temperature which is ultimately more important than ambient air

Plant temperature is seperate to air temp and how the plant cools by being hotter than the air.

This is the radiation which heats the plant not the air then the plant transpires that heat into the air.

If air warmer than plant plant absorbs heat :-)

Well evaporative cooling through transpiration but yes

So what if running a 100% led that do not emit ir radiation? Typically you would actually want to run yours temps a little higher but would you get more accurate readings since there is no radiation?

Thanks for all the advice everyonne.
Extraction & internal fan. I was told the few hours at night its around 60-64% is ok. i have my tent against a radiator at night to keep the temps up & a tube heater between the two pots & touching them both at night as well.

I really appreciate your reply!

Im in Ireland & its winter here & damp-ish the last few days. Im growing in a 2x2 tent. I've been moving it into my living room at night as I cant sleep with it in my bedroom.

Is 66% way to high for a few hours at night?

Last summer I ran few strains that produced dense big buds. I mean dense. Never used a dehumidifier and it was over 70% most always. Not a sign of mold anywhere. Keep the fans blowing..even at night last few weeks. I got a bit lucky but you should be ok at that rh
