Wow, that’s nuts. I’m currently at 75 and 40%. My exhaust fan is running full speed constantly. And I have to put heat in or it drops lower. By the way, I’m in Michigan n it’s cold here. But in the summer I cool my main basement and pull the cool air in through a furnace filter (two actually) that I cut the door to fit and duct taped to the door. I know, it’s low tech, but I have had great success with it. Oh yeah, I’m in the basement as well.

It’s pretty regular, a little on the high side as far as humidity. Add another dehumidifier, it sure couldn’t hurt. Can u exhaust the dehumidifier out of the space too? I mean I would definitely want the rh lower. It does seem steady, just high, so maybe ur just not able to get all you need outta a single dehumidifier. A five degree swing between temps isn’t a big deal. My girls go through way bigger changes no matter the season. My room is in the low 60s at night and mid to high 70s during light hours. And they love it. So go after the humidity and the temp swings will get shorter too.

Got it resolved! Haven’t seen it work during the night time just yet, but we were able to program the AC so that it doesn’t use the fan mode.. so far so good let’s see what happens when the lights are off. I’m working on exhausting the dehu for sure.

I was going to say there has to be a way to turn that thing off of auto! Well I'm pretty sure that was your culprit hope it fixes it good luck to you

Yes! Took many tries, but we need to do bypass the fan operation from the unit. The controller didn't have this option. All is working now.. Keeping stable conditions!

Humidity is rising and it's not from the AC. I'm watering 25 - 35 gallons daily. At nights when they're asleep my co2 naturally gets to 1300 - 1400. I'm keeping my room at about 76 degrees, but I can't control humidity. I've got about 4 thermostats, each one is reading at an average of 73 - 76% humidity again.. I don't know what's causing this.

Oh no thats not good , are you mid flowering ? Maybe u should have fresh air in and out at night it will also get your co2 ppm down at night that's actually better to do anyway because at night they don't use it .

To also keep humidity in check

Edit : are u experiencing the spike furring day or just lights out?

I would be trying to create more circulation for sure. Adding fresh air will do wonders for you. If your worried about it being cold... don’t be. It will make your ac run less at the worst. And you can use a carbon filter to keep the incoming air clean. Win win. You can add a small heater to keep temps up at night if necessary.

Also dehumidifiers are not flawless... is yours working right? Maybe a filter is dirty or it’s in need of service? And are you sure it should be capable of working the load your putting on it? Do you have any idea if it raises after feeding n how long after? There’s a lot going on you know. But truth.... I would get fresh air comin in... sealed in no way means no fresh air. It means no bugs and you control the environment, like how much fresh air you add, just my opinion.

I too have struggled with environmentals. Temp and humidity monitoring has helped me tremendously.

had the same issues awhile back, now use Ink Bird Temp and R/H basic controls , ditched the aircon, humidifier and no Co2....
what works for me these days - 4 x 1.6x 2.4 x 2.4 rooms,Passive intake, 8 inch extraction and filter per room, dehumidifier, 2 fans and leds , have a 6 inch fan/filter sitting out side under cover pushing cool/fresh air in from out doors ... Like to keep things pretty simple these days, get very good results and still learning :joint:

I also have no co2 no ac and no dehumidifier. I have a wall mount n a box fan in room n 8in filtered exhaust. Pulling cool air from main basement area passively. Summer will require A lot less ac than a 100% sealed room. Goin low tech this time as well due to realizing if I’m pulling cooler air in passively it will take less to maintain the room. Has actually needed a small heater on the coldest nights to keep temp up. Now that the temp is rising I no longer need the heater and the room still holds steady lights on or off. In the heat of summer I will use air in the main basement area (220v unit) and will be in good shape. If I find I need to I will run the 8in to the chimney and remove the filter. Allowing more flow, additionally I can put a fan in front of the passive intake (furnace filter duck taped in the door to allow intake of air and nothing else) and force more intake. Just a rundown of what and how as far as my personal setup. Oh ya n I’m running led’s also, so a lot less heat

I've got 2 4x16 tables, and 1 4x12 table and 11 LEDs. I'm using a 180 pint ideal air dehu. I've got about 8 fans up high and no air from outside. At nights the temps are about 75 and humidity is about 75 - 80. During the day, I'm getting the about 76 - 77 and humidity is about 70 - 74. I did have some water leaking out one of the trays today. I noticed it had been wet for about 2 days. I've dried it up, I've vacuumed the room after it's feed today. As of now, the temp and humidity is stable at 76 degrees and 71% humidity. about 140 plants, week 1 flower, they're about 4ft tall, in the process of pruning and deleafing which I'm assuming will help because they are VERY bushy and I feel like that's trapping air flow and light to the tray for extra drying of excess water. I've added trays under the leak to prevent spread of water. Dehu is set to 45, it's getting to about 58 - 67 on it's thermometer and it won't get lower as of now.

I'm thinking of adding 2 more ground fans to run beneath the tables to create more airflow in the room. I'm working on keeping the leakage to a minimum and drying out as much as I can. Prior to this, when the plants were 2.5 3ft tall, less bushy, eating less, the room had no issues humidity wise.

Take what I say with a grain of salt. I've got a sealed room, its pretty dialed in but I use an exhaust at night to keep humidity in check. I'm just throwing ideas out below....

- You need a bigger dehumidifier. You're running LED lights, you will require even more dehumidification than if you were running HPS lights. If your watering 25-35 gallons a day, that's approx. 200-300 pints and your running a 180pint dehue.
- Get a heater in that room and get the day/night differential close to the same. Your day and night temps along with humidity will stay consistent.
- Not sure how you're supplementing co2 but if your controller has a photocell than your best bet would be to hook up an exhaust fan in your room connected to a humidistat. This is what I do and it keeps my light off humidity perfect. My Co2 controller has a photo cell so my burners don't turn on when lights go out when room starts to exhaust at lights out. I've noticed it only really exhaust for more than a few minutes right when lights go out. After that initial purge the exhaust only kicks on a few times per hour for a min or so.

--I was thinking this as well, but originally the room humidity was under control. I'm not sure what has changed, I was feeding about 40 gallons every 2 days, now I am geed about 25 - 35 gallons every day. Also, when you go into the room it doesn't feel like 71% humidity, it feels much less, but all my readings say 71%. This def make sense though, I'm adding a air mover to see if I can create more air flow to see if it helps. If not i'll need another dehu.

- Get a heater in that room and get the day/night differential close to the same. Your day and night temps along with humidity will stay consistent.
--My system does have heat and ac modes. My dehu also adds about 108 degree dry air while it's running. I don't want to sound stupid here, but what exactly would be my approach in this step?

- Not sure how you're supplementing co2 but if your controller has a photocell than your best bet would be to hook up an exhaust fan in your room connected to a humidistat.

I've noticed it only really exhaust for more than a few minutes right when lights go out. After that initial purge the exhaust only kicks on a few times per hour for a min or so.
--As of now I've unplugged my CO2 system completely. I'm getting about 1400 at night, and it gets down to 300 at night. I've unplugged it to find out if it's leaking or it's not leaking.

I'm using the below for the regulator and controller. The Atlas 3 has a setting called F11, this is for day time enrichment. It does have photocel on the front if you look at the product page.

I've been able to vacuum most of the water off the trays, and the spillage. I added another 50/80 pint dehu. As of now I was able to lower it to an average of 62. Still not going to cut it as I am moving up in flower into week 2. Exhausting air as of now is not an option, but I was thinking about adding more airflow. I added a ground floor fan. I'm thinking of adding 4 more wall fans in the room. I only have 9 as of now sitting up higher than the trees. I'm also considering adding another dehu, but it's SO expensive as of now.
