dehumidifier in the room, or outside the room?

[Jeffro420]

Hello. My question is should I have the dehumidifier inside the room or outside? It's a 14'x14' room. It has three 1000 watt hps' s. It has a 8 inch fresh air intake fan and a 10 inch carbon scrubber/extraction fan. Should the dehumidifier be where I pull my fresh air from? Or inside? My only concern with it being inside is added heat, and the dehumidified air being sucked out. Or does it really matter where it is? I added a drawing of what I'm working with. Thanks.

I rig up a bit of ducting to the outlet on my dehumidifier to the inlet in tent

Mine sits in the air source room.

Should not have to run it when the lights are on so the heat should not be horrible. Mines in the room, but my room is in a pole barn so that is my only option.

put it in the room. and the exhaust blows out of the room . build a half wall if you will . or rig it up ducting

The exhaust from the DH, IS the dry air!
I run as closed an environment as I can. If I ran Co2 I would do it even less, as it would be a generated gassing by controller and the controller would turn on and off all air exchange and cooling. I would not use a DH in gassing !

Is your room exhaust on all the time? In my book your turning your air over more then you need to! I only exhaust once an hr, and just enough to turn the room air over 1.5 times! With my fan power and room size that's about 5 min. per hr.

Put it IN the room !!

Some AC units, like central, portable and window rattler's, will reduce the RH too.

that's how I used to do one of my rooms shot exhaust out side the dry air . and my room still got dry and stayed cool. I had a natural gas co2 burner . yea . I could see if you had a bottle it would waste the co2 for sure

Im debating this now too. Bought a 70pint for my 5x9. In or out?

If you duct it in would you not be creating a positive pressure in the room/tent. Would that not require more exhaust to put the tent back into a negative if filtering air? What a tangled web we weave lol.

IN! The DH is taking it in wet and putting it out dry- No pressure change in the room!

Anything else is a waste!
