Humidity Is Too Low In Flower Room, Help Please!!

[the gnome]

Ahah, thats what I'm thinking as well. So damn worried about too much humidity, PM, mold, etc...

Not worried enough about vpd, transpiration, etc... Critical plant biological processes...

Its a learning curve

I'm with ya on that one dabs,
i guess this is the *dialing it in* part I've read about for
the last few years hehe.

its definitely a balance that you have to master.
still, with the new room ... I love it!
i still have the kid in a candy store mindset

Are you guys spraying on bare walls?

 

[the gnome]

concrete floor here...

 

[Coconutz]

Might wanna drop some bleach down and see if it fizzles.
If it starts smoking and shit you have mold

 

[the gnome]

Ive had a mop-n-bucket in the room for cleanup since the room, went online.
w/bleach and were good on that one
not only that but the room was bombed to hell and back w/fungaflor before any renters came in.

i don't like all this water shit to raise RH because of the mold issue your mentioning
but i have to to what i have to do atm
and very good post on yer part bringing up this point,

 

[Coconutz]

Ask me how I know?
No... please dont. I dont wanna think about it!
Fucking temporary res without a float valve. pfff

 

[DabOnDabs]

i spray directly on my walls but its silver foam insulation...

Also, Im not too worried about mold because it takes about an hour for it all to evaporate and become dry. Will add some bleach in the next couple days to take care of any nasties that might be brewing. thanks for the heads up coco NUTTSSSSS

Well when I went last night, the humidity had risen up to 58%, and then started to drop after the lights had been on for an hour or so. So....... I turned off the Ac and started pulling in air from outside. So once again later today I will see what's up and if changes need to be made. Next step will be to put soaking towels all over the place. I run perpetual so I'm aiming to get the rh at 60% and try and keep it there. I have 5 fans moving air around in the room, so I'm not really worried about mold. The saga continues......

i bought $550 worth of DEhumidifiers to take moisture OUT at nite and now have to spend $250 to put moisture back IN during lites on... a labor of love fo sure.

Just wondering what you decided on for a humidifier ?

I too am fighting low rh. This is for a small 5x5 closet for flower with 1kw light. I have a small wick type right in the closet and a larger 3 gallon wick type blowing in the door of the closet with a panda plastic shroud so the moisture goes into the closet and it just isn't working. It's 91% RH outside right now and even when it's raining out i can't seem to get it past 40-45%

On top of that i'm battling the 2 spotted little bastards I want to get the rh up so i can use predatory mites.

Just when you think you have control they take over again.
I feel like i just got punched in the gut. Totally depressed.

hola' somerandom,
cheer up ma man!
its not as bad as you think....
I don't kno the specifics of your grow but the reason its 91% out and barely45% indoors is because that 10000w lamp is burning off all the humidity,
a 1kw lamp in a 5x5 is the culprit I suspect.....is it air cooled?
if not it would help some but its still a small area for that kind of heat in that area, humidity wise
I doubt wick huey's will cut it
you need some ultrasonic foggers for your situation imo

now i'm still new to controlling the humidity thing i my sealed room but i"m learning real fast.
the humidifier ive got incoming is too big for your 25sqft
they have these pond foggers that would probably be ideal for your situation...
I'll find a link to the thread we were just discussing it yesterday

Thanks for the response.I hope I'm not derailing the thread. The closet may be more like 6x5 but yeah it's not that big. The light is sealed and air cooled. It doesn't get much past 80F in there in the winter.Usually lower.I'll dial the digi ballast down to 750 and see if that helps.
I'll have to look into the pond fogger. The larger ultrasonic humidifiers i have been scoping out have pretty small tanks and are pretty expensive,that's why i asked what your getting. I searched on here for recommendations but din't really see any threads,Just the hydro fogger. I just ordered a bunch of beans from the bay and i have to get rid of these mites,man i hate them.

 

[frankenstein2]

Update: The rh sits between 50%-60% during lights on. I unhooked the ac and turned it's exhaust fan around to pull in ice cold air from outside and it's working like a dream. temps don't go above 83 now and the lows are staying higher as well. I think I'm gonna get a damper the works on the fan pressure to hopefully bring lights off temps up a bit. Right now it dips down to 65, and I would like it no lower than 70. Thanks for all the help guys.

I got something like the hydrofogger, same thing different label and $30 cheaper @PLH
it hooks to 1/4" tubing for constant feed.

spinosad works on mites and other critters,

btw , forgot to ask...
are you having probs from low Rh?
are you in bloom or veg?
until I went w/co2 low rh never gave me issues


i had a bad thrips prob, one spray with spinosad and that was it.
are you in veg or...?
Volck oil will take em out fast plus its an ovacide and works on other bugs and things like PM.
becareful, you can burn plants with it.

Looks like OP got his problem solved and dialed. That's what I'm trying to work my way up to, with what i have to work with.

I looked up the humidifier you're getting, looks nice i bookmarked it for when i have a proper space.

I'll have to see if i can get some spinosad and see if it works for me. Can you use it in flower?

I try to do a perpetual with anywhere from 5-8 strains. All in different stages. It's a PITA but i like variety.

The mite problem is not totally out of control , But one is to many. the problem is mainly in flower , but have some in veg too. I just want healthy plants

I'm not sure if I'm having problems caused by low RH.

I know mites propagate rapidly in low RH.
I bought a big air pump and want to try to use OGBiowar.
it seems the people here i see using it have super healthy plants.
Mites go after the weakest plants first. OGBio war only works with higher humidity , same with predatory mites and most likely a lot of other things people try to use. I'd be happy just to maintain 50%+

I'll have to see if i can get some spinosad or Volck and see if it works for me until i get this RH problem worked out. Can you use these in flower?

I,m buying new filters and taking this big POS humidifier back and getting either an ultrasonic , or a multihead ultrasonic fogger.

I have low RH in veg too which are in a different room under t5's and pl-55 tek where heat isn't an issue. I jsut can't understand why it's so dry ,when it's wet or raining outside.

I'm just trying to get as dialed as i possibly can for the space i have. You would laugh or maybe cry if you seen what I'm working with lol. When things go right which is rare i do pretty good for what i have.

 

[the gnome]

how far along in bloom are you?
never tried ogbiowar
usually if your in flower there's not much you can do unless you get the predator bugs that eat mites.
volck oil is out if your in bloom.
spinosad, you can spray on your veggies up to 3 days before harvest,
but veggies get washed,
if your still in stretch/very early bloom you can still do something.

Ive used 70% iso alcohol and *lightly* sprayed my plants in early bloom.
it killed the mites and eggs, but there is a line between killing mites and frying your plants.
it didn't take much and the mites were history.
but, iso will melt your resin heads, so again very early bloom if your try this one.

if your going to spray anything on your plants for pest control do it before you flip the lites, and keep it as clean as you can till chop,

no pest strips will work well, it releases dichlorvos gas and is effective, but there are some that think it will contaminate your final product.
you need to look in the infirmary, there's tons of info on mite control, organic and non

 

[the gnome]

I completely forgot about the heat treatment method.
a bunch of us had broadmites and i guy...retro? maybe came up with heating the room to 115-120F for an hour, it will killem and eggs for sure and the plants are no worse for it.
check the infirmary in one of the broadmite threads

So I filled the extra res I have and put a floor fan blowing across the to of it. Later today I will find out how much it helped. The Ac is on a timer that goes off when the lights go out. It also has it's own exhaust fan pulling the hot air from it out of the room. The Ac also dehumidifies while it runs. So I had the brainchild last night of shutting off the Ac altogether and turning the exhaust fan around to pull ice cold air in from outside. I think by not having the ac running and pulling humidity from the air and putting extra water in the room I might just solve my problem. If it's two much I will get rid of the extra res of water and see where we are at. If it's still too much(i.e. during lights off) I will put a dehuey in there.

try taking a bath towel and draping it vertically above the res, with just the bottom couple inches sticking in the water, this will act like a wick. blow your fan past the wet towel as it much much more efficient than blowing it across the water surface.

i used to have that problem but i installed some solenoids with mist heads on them which is controlled by my humidity controller and a 1-10 second setting on a on\off timer.

 

[RoadRash]

Growing plants themselves are humidifiers.

I wonder what effect slowing down the exhaust fan would have.

To lower the rate at which humidified air is leaving the grow-space.

 

[frankenstein2]

I don't exhaust air from the room. The only air that leaves the room is when I open the door. The lights are in a sealed closed loop, that brings cold outside air through them, and back outside.

just an update on my vpd/low Rh probs.
Ive yet to get my humidifier yet.. the other 1/2 of the order came in
BUT
Ive noticed the past 3 days i haven't had to spray3-4 Xs
but 1-2 times daily
today Rh is hovering between72%-79%

Growing plants themselves are humidifiers.

yup roadrash.... the room is constantly in flux as the plants gro and its a balance from day to day.
I sprayed once yesterday and doesn't look like i'll need to anymore til room dynamics change... but its about to real quick.
1/2 the plants i the room are 4ft they are heading to another bloom site to go immediately into 12/12

this will leave the 18-24" plants giving them more lite and room to expand on the lateral growth
