Coco and humidity. Help me out please.

[Forbinwasblue]

Hey there people. I’m on my first coco grow. It’s cloud coir, 50/50 coco perlite. 14 1000s. 71 plants in 5 gallons. My humidity is pretty high. With the lights off, it got to almost 70% today so I went and bought another dehumidifier. Now I have 2 70 pint dehus running in a 32x22x10 ft room. The lights are on now and it’s saying 58%. I’ve been feeding everyday, 60 gallons through the 71 5 gallons. So my question is should I stop the daily watering to keep humidity down? I’m terrified of PM again, I got it pretty bad last round in soil and had to completely redo everything in my room. I’m at the end of my first week of flower today. I haven’t watered yet this evening and trying to decide if I should. Thanks for looking.

Do you have film or foil on the walls?

I’m not using anything reflective, other than white paint in my closet, and this environment has reduced my RH issues dramatically. Game change.

You should consider investing in larger (commercial) dehumidifiers.

No film on the walls.

I was thinking the same thing nrthrnmichigan.

Hi Dave...I was just curious as to why the wall covering would make such a difference regarding RH?

Also I'm with the yooper on getting a commercial unit.

You should keep your coco wet. Dont stop watering. As suggested invest in a bigger dehum. but 58 on its own is not bad ime. I have been growing in 60-65 for a year, never had a pm outbreak. But i’m a hobby grower so not much invested and nothing is expected in return.

Definitely keep coco wet, if they dry out then they get all kinds of problems then death. I'v let my coco room get to 55/60 rh recently (in flower) and am using less water to feed before run off. Keep the air moving to allow NO micro environments to develop around any plants. How many fans do you have running in that room? What is your air exchange rate? Is it a sealed room? PM sucks balls...been through it.. Look into UVC if it persists

I’m pretty certain that the walls are sucking up humidity.

In my tent I fought high humidity.

You run 14,000watts over 71 plants and your asking advice here....

Thanks Dave...that may be true, depending on how the wall is built. My room was built for high humidity with a vapor barrier directly behind the sheetrock, whereas an interior wall would have no vapor barrier...thus allowing more free movement of moisture.

I’ve got 4 oscillating fans. One stationary. 12 inch exhaust and just switched my 12 inch intake to a 6 because it’s so damn cold up here.

There’s always room to learn King. 14,000 is a hobby for some people. I just take my hobbies seriously and don’t like doing anything halfass or small. If you’re gonna do it, do it. And like I said, first coco.

@Forbinwasblue Do you have those dehumidifiers on continuous and turbo? I found my 70 pint needed to be on turbo mode atleast and sometimes continuous.

 

[wizard cabbage]

That’s a farm

 

[Forbinwasblue]

They’re running full time on max.

I'm using 100 pint Ideal Air. I know there are better ones out there but couldn't pass up a deal on 3 of them, they seem to work pretty good. 1 in flower (36x24x8 ) 1 in veg and a back up. Once in a while, usually in spring or fall we have to run a second unit in the flower room.

lol I doubt lining the walls with anything will drop your humidity levels... that doesn’t really make any sense to me.

You have a lot of plants and, it seems like you’re already doing a fairly good job of keeping the humidity down.

I agree with most people on here about purchasing a commercial dehumidifier. The humidity levels will continue to rise during the flower cycle.

I hope your air circulation is sufficient, good luck man!

 

[Forbinwasblue]

Thanks everyone. I appreciate your time and knowledge.

So explain what you intend to do with over 10kg of weed every flowering cycle?

I see concentrates in somebody's future. Not that it's any of my business.
