Dehumidifier

70% RH at 85F for LED grows is optimal. Gotta keep that RH consistent, however.

HID grows prefer cooler temps, just below 80F, RH around 65%.

I realize those RH numbers are a lot higher than the conventional wisdom but they're backed up by botanical science and agronomy.

Alrighty and then do you make the decreases in temp and humidity in the last 2 weeks or so of flower time?

Yes, although I've never found it necessary nor have I ever noticed that doing such things improved the final result.

Would you consider temps 77F RH 60-65% at night with good airflow a problem During flower? I’m running a 3x3 and debating if I should get a cheap dehumidifier to run at night

With good airflow , you are fine. Its certainly not worth going an buying a dehum just for 65% at night. sounds great to me.

Depends on the strain, a very dense indica hybrid could be a problem.

IF you let it. If its stuffed in the corner where RH is 80 or 90 at night then yes , it will happen. but if its 65% in the wettest spot in the room With plenty of airflow then it wont happen. RIU does a damn good job at keeping us all super aware of mold issues.

I am looking for something quiet that will keep humidity low. I see the Pro Breeze being recommended too, think i will take a look at that as well.

you should calculate how many pints per day you need to remove.
