I just got a humidifier[bionaire argos]and i wan't to know where's best to place it ?

I've got 2 chambers,one for the main veg/flowering and the other for mum's/cuttings.

I'm 5 weeks into 12/12 in the main growspace,but i've got some cuttings in the other one.
Obviously one wants higher RH than the other,but how can i get both chambers to get different RH ?

I've got an rvk 125 inlet and 150 exhaust both on dimmers.
Should i put the humidifier somewhere in front of the inlet ?So it sucks in more humid air ?
Or am i supposed to have it in the growspace,when i veg again ?

My place is off the scale for low RH,as it's so dry even the flowring AK seems to like the more humid air i've provided today.[5 weeks in]They definitely look happier after just 1 day of more humid air,but i'm fully aware of the dangers of budrot and won't overdo things with RH.
Obviously nearer harvest i will want a much lower RH in there than my mums/cuttings would like,so how can i supply both chambers with the righ RH ? both now and in future ?

Can't get my head around this one at all

Ask for more details of my grow if you need them.

Hi Deanbo,
any chance you could furnish more details of your grow.What vents into what and where does it go?With your current set up it sounds like your 2 fans are between them servicing your grow and veg area,which would mean RH is gonna be samey in both rooms.If you can split your extract with ducting so you have air being pullled from both rooms,that might do it as you just put your humidifier into the veg section.

Not too sure though,need your growroom details squire.

OK Rockster here we go.

I've got 1 growspace 36" X 31" X 7 feet high.
And another smaller one 24" X 24" X 30" adjacent to it.

They're arranged like so;

The main 7 foot high one has 3 compartments on it's right.The DIY CF roughly 22" X 23" X 30" at the top.
The mum+clones part's in the middle and the fans at the bottom with an empty compartment directly under the mum's bit,which is sealed from any possible water getting in at all,as the fans are to the right of it..
My ballast is outside of this and i'm unsure of where to place that too.

The exhaust leaves the main chamber top rear[on the side panel] right as you look face on at it,and the inlet[main chamber] comes in bottom right front,again on the right hand side panel.

It's made like this so the inlet fan pulls in cool air and vents into a chamber underneath the mum's/clones chamber,which supplies cool air to the main one by the hole on the right panel and the top of the inlet chamber is the bottom of the mum's/clones bit with a hole in the centre through which the inlet air is pulled upward into the mum's bit.
On top of all this sits my DIY CF and the exhaust from both chambers enter it seperately with 6" ducting from the main chamber and some soil pipe for the mum's bit..
It then leaves at the top through the CF and down to the rvk 150 venting exhaust to the wall cavity.

I haven't been able to make a hole for the inlet through the wall as i intended,so i removed the boards off the window and opened it,drawing in cool outside air.
It won't open fully,it's not made like that it's just the top part of window that opens and i leave that open to get the cool air in.

From your reply i gather i can put it in my growspace OK,but i don't need it so much in there.
I need to raise the RH in the mum's bit,not the main chamber.

If i split the box that's between the fan and inlet holes for both,and place it in there it might work but i won't be able to access it to re-fill it then.

The only way i can see to do it is place the humidifier in the mum's bit,as at least i can get to it.
I'll have to redo a few things though as it's a bit big for in there.

At the moment BOTH chambers seem to like the higher RH,so just for now would the best way of doing that be to let the inlet ducting suck in air that's humid from the humidifier ?
It won't harm the fan by drawing in already moist air will it ?
It's not right next to the ducting and a fair bit of steam doesn't get sucked in,that's how i've been doing it up until now and they look better already.

NO camera i'm afraid Rockster ,so that's the best i can describe it hope you can understand all that.

Hi Deanbo,
sorry 'ol bean,but I can't quite make out your system set up.Your AK's are 6' tall if memory serves so they must be in the 7' chamber yet you say it's compartmentalised with a mother/clone section in the middle.What is the smaller chamber,adjacent to the large one doing?

It is 8.45 and I'm barely through my first cuppa of the day so please excuse me for not being able to visualise the whole caboodle.You hav'nt got a scanner have you?A drawn pic would help.For the moment I can only say that you have no worries pulling moist air through your fan.

Sorry I can't be of any help atm.I'll put me head back down for an hour.Who knows,I might have a eureka moment.

No Rockster the mum and clones bit is THE compartment next to the main 7 foot high one.

The main 7ft high one is just 1 growspace.

the mum+clones space is in the middle with a CF above and fans and a kind of box i made BELOW so i can have the inlet fan feed BOTH spaces.

I'll have to install my printer/scanner to do a sketch but if you can imagine 2 X 7 ft high and 3 ft wide growspaces.[the one on the right's only 24" wide not 36 ",but you get the idea.]
The one on the left is the main one,and the one on the right basically consists of 3 different parts with the mum/clones part in the middle sandwiched by the CF ABOVE and fans and the inlet[maniflod ?] BELOW.

When i cut out the holes for the exhaust in at the top and inlet below i saved the waste,which are wooden circles and i've screwed 'em on so i can slide them over the holes and open or close them up for more or less flow.
I found the mum/clones part needs much less airflow than the main one but with 1 fan,that's the only way i could think of reducing the flow into it,whilst still getting good airflow through the main chamber.
