reduce humidity
massivetidsanswered grow question a year ago
There are really only just 2 ways to bring down the humidity.
The first option is to bring more air with a lower humidity inside the tent. You need a larger exhaust fan and the air inlet should ofcourse have a lower humidity.
The second option is using a dehumidfier. The dehumidfier should at least be able to suck up the same amount of moist that your plants evaporate in able to keep the humidity low.
Next to those things it is just a matter of do not overwater and let water sit still inside the tent/cabinet.

The best way I've found is your HVAC system in your tent. Setting the controller 69 at you specific humidity and let the fans expell the rest

maybe a whole shit load of calcium chloride? it's used for de-icing roads and sidewalks, but it's basically similar properties to what you get in those 'dry-packs' they put in some products to reduce RH. It will absorb moisture from air, and you'd have to replace it at some point... you could figure out capacity by weight it.. if it stops gaining weight, it can't absorb any water, and you can work backward from that timeline for regular maintenance. How much it pulls out depends on how much you can put down - surface area being important too. hang some bags, line the floor, lol.. you'd probably need a ton iof it, and it'd be sloppy and wet when you remove it.
the point is... you need a dehumidifier to control RH. if the ambient RH is high due to season of year, then you cannot do anything but use a dehum.

Ventilation set upI just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?Setup. Ventilation

Won't Oscillate AnymoreI was wondering what type of oscillating fans that everyone uses in small grow tents. I have been using the Vivosun fans and since they won't last I'm looking for alternatives. In case it matters I'm growing in a 27x27x63 MarsHydro tent.

Low humidity issueTents 20'' × 30''. Using a vivosun 6'' inline fan to exhaust with passive intake to create negative pressure. I have a good humidifier but even on full the rh doesnt go above 40%. Not unless the room the tent vents into becomes super humid as well.

My temps are great at lights-off, around 71-73F. I can put a big dehumidifier in, but I don't want to yet. Any thoughts?
