Question about dehumidifier for 3x3 tent

Hi I’m trying to get my humidity down what size dehumidifier do I need? I have two already that remove 9 oz water a day. My humidity keeps hitting around 60%. I read that they should be hung by the light? Mine are on the floor right now. Any suggestions would be appreciated

@Worleyhead What is your environment like? Is the 3x3 in a very humid room?

I’ve got a 90 pint dehumidifier in the room I grow in. It’ll pull 5+gal/day to keep the rh at 45%.

It’d heat my tent up too much if it was in there, plus it’d probably be running constantly because of the air exchange.

Humidity will be lower at canopy level where it is closer to your lights as well best to use a probe on a steak to tell how the plants feel also don’t forget to match ur VPD to temps or vise versa if u can’t get humidity where u want it

Happy looking gals :wink:

Not sure what VPD is…this is only my second garden, my first started in March and near the end started running into humidity issues and found small spot of mold/bud rot and harvested immediately, didn’t lose much at all because I caught it right away but my trichomes were half clear half cloudy. Anyway got 7 1/2 oz and it has been really good smoke hoping to keep humidity down so I can finish these girls a little longer

My first harvest

I did notice the humidity is different closer to light as I put a hydrometer up high and it’s reading about 5% lower than the one on the floor

I have another in-line fan coming today, right now I just have one hooked to carbon filter exhausting air I’m going to hook new one up to draw air in so maybe that might help me I hope

Hey Worley, how did that grow turn out? I’m running into high rh levels in my 3x3 (65% average), week 1 of flower. That’s about where I want the rh to be for the stretch, but afterwards I’ll need to drop it. Looking into a dehumidifier that’ll take that rh down to 40% for late flower. Any suggestions will help.

Setup:
•3x3 tent w/ 2 plants in soil
•HLG 550 V2 RSpec, 22” from canopy @ 100% power
•G8 LED 90 Bloom Lamp
•AC Infinity Cloudline 4” exhaust w/ carbon filter
•Passive intake, air conditioned room

So I know it’s been awhile since this post, but found it in a Google search, am I supposed to have my dehumidifier up higher to be doing the job? Cuz right now it’s been on the floor for a few days and hasn’t even filled up once yet, it’s my THIRD dehumidifier I bought cuz I keep thinking their not working or not strong enough, but I think after reading this, it’s actually where I have it, I need some insight please and maybe suggestions on a dehumidifier that will work in my 3x3x7 tent.

Just curious what is your RH reading?

@Chasworks it sits in the 50-57 range now, since that post I’ve figured out a way to keep everything stable, I just stabilize the room my 3 tents are in, and keep the doors open, much easier that way, I’ve heard of it referred to as the “lung room” as it’s the room that you have to keep breathing right, to keep the tents alive!! Everything is going pretty well!!
