rH problems with martha...

I cant get my rH to drop below 96% in my mini-martha. I use a coolmist 2.4 gal mod, and i really dont wanna add a ton of new holes as i have already done so. I know it's probably due to too small of a volume of air (downsized my 3 shelf martha to one shelf thats double the surface area.)
Im just blanking on the rest of those tips and tricks to bring my rH down...

I had the same problem with my Martha style set up because it's pretty small.
I just put my cool mist on a timer. It comes on and off every half hour. I also have found that by leaving the door to my set up loose I can help control how much humidity builds up.

no no no... the CM has to run 24/7...
im thinking about getting my old fish pump out, taking out the high level holes in the set-up and running a little filtered 60% rH air in there to mix with the coolmist's 100% which also pushes alot more volume, hopefully i can get some sort of poise here. Any thoughts/suggestions?

Try adding a fan somewhere in the mix to help dry up the air and to increase fae.. or leave the top zipper of the martha open so humid air can escape

i threw a HEPA in front of it so that air is passing through my poly-fil in an airation attempt.. but maybe i could add a computer fan somewhere.. preferably on the bottom to expunge more CO2? or the top to get rid of more humidity? i shall find out.
any other suggestions are much appreciated...

one thing i tried with my martha was to run my coolmist dry, with no water, and just use a humidifier for RH.. but since you have the modded coolmist and no humidifier, I dont think this would apply..

well a coolmist is a humidifier... im assuming your speaking of an ultra-sonic? sounds like you'd achieve quite a bit of FAE that way but running a 2.4gal CM dry is alot of air circulation to humidify, i dont believe i would have the means to do so... isnt that bad for your CM too?

One of the main points of having a martha is having constant FAE. Putting the CM on a timer takes away (in that case^^) half the FAE... and the more FAE ya got, the faster you get pins, and the faster your fruits grow!

Well I'll tell ya it certainly does not have to be on 24/7 (Fact) for optimal pinsets. But it sounds like you are an experienced mycologist already so never mind me I'm just an armature. GL my friend

hyphae... you have definately given me a great deal of good info and i would never consider myself more experienced than yourself, but i have also found that when you put the CM on a timer the rH doesn't really drop. The air circulation just stops and rH maintains unless you have additional movement. I would like to accomplish maintaining the highest rate of FAE possible, which is why im trying to figure it out this way. I do greatly appreciate your input

Are you using perlite at the base of your Martha? Maybe you need to not have it sealed so well? I've seen tub setups that provided totally awesome flushes with only a half a dozen FAE's per day. You have alot of options here ya just have to do a little fine tweaking is all.

No perlite.. but the surface is filled by two 10x20 casings which is whats throwin my rH so high... i guess the extra holes are my only option. I currently have 6 1/2" CO2 outlets (on bottom) and 4 3/4" holes on the top for i would hope to be rH outlets/FAE inlets.. seeing as how my rH still wont drop below 96 i think ill try opening some more airflow up top..

what type of hygrometer are you using? have you considered the fact that high rh can hinder the results of hygrometers, maybe you have less rh than what is really showing?
when was the last time you used the salt tek to calibrate your hygro
just a thought...

thanks for the concern but my rH readings are correct.
I use 2 digital hygrometers, that dont need calibration.
1.non-brand digital hygro/temp 2.Lacrosse Technology WS9032-u wireless weather station (which there are 2 sensors in this FC to make a total of 3 hygros throughout)

You could have a small fan blowing air directly or indirectly at the FC. This will bring down your rH and help with FAE. Of course you could also use a small PC fan and connect it to your set up. This would require you finding a powder supply for it. I think most of those fan run on 12V DC at about 100 -120 mA.
I once saw a set up where a guy took a small PC fan and connected a rheostat to it. This way he could control the fan speed. The fan was connected to output of a coolmist (a PVC pipe he had running into his FC). This way he could fine tune the air mixture going into the FC.
