Resurrecting an old thread because I am, too, battling humidity at night at the moment. I am hoping for, and open to, other suggestions on humidity management here…
Running up to 64% lights on, and 83% lights off. Here is the tent:
There are 3x small fans blowing on the canopy right now, and they are doing a pretty good job at moving shit around.
I have it, and another tent, exhausting together outside, like so:
Unfortunately, the humidity in my basement is around 60%, so the replacement air is not great.
I have tried putting the dehuey in the tent, but it heats up really fast. Much faster than can be evacuated. I am running air cooled hoods too. 1kW HPS.
So now, i am trying this:
The output of the dehumidifier is being partially blown into the tent. through a loosely attached 4" duct. It is working pretty well – air cooling is keeping up with the temp, and the humidity during my test went down to 52%.
Not that concerned with lights-on @64% because VPD is still a-OK, but lights off gotta do something NOW. Just entered week 6 and loaded PK, so things are gonna get dense and moldy right quick if I snooze…
Anybody else had good luck regulating tent humidity in rainforest climates? BC, PNW, UK etc? Even with the fan full tilt lights out, and ambient at 60%, in the tent it is 83…
I often hit high 80s during lights on with no Ill effects. Normally it drops to low 70s lights off. I’m running auto pots so coco constantly wet and humidity does get high. As long as plenty airflow on lower section of the plants you should be fine.
