i got a cool mist and an ultra sonic left them both on at seperate times over night and cant get a humidity reading over 68 there is actully a fog mist u can see and droplets forming on sides and floor and still dont read over 68 with either set up. now i thought it was my humistat and i took it back talking shit to them and they gave me another one and the same thing so i dont now what to do. how do i get my humidity up to 97% is there a visual way to say its about 100% or what should i do to try to get it up to that?

If it looks foggy and the walls
are dripping you're in good shape.
Dont take this the wrong way but
that gauge you got is most likely
crap. Nice ones really CAN NOT
be found at wal-mart type stores
or petstores. Even radioshack
digitals stop at like 85% or are
not accurate.

if you are doing casings then you really don't want the walls dripping wet.
cakes yeah, sure
but not casings.
how do you have it set up, what size chamber, etc. the more details the better to help.
you can get a good hygrometer at http://www.torka.com
get a hair hygrometer, polytherm german made mechanical for about $40, lasts years.

hippie glad u answered ! ok heres my set up i got stright hay(not cased) in a chamber i made out of peices of plex. glass its about 2 1/2 feet tall and 5 feet long. now i have a ultrasonic humi. and a cool mist i can place either one inside the chamber and the ultra sonic will flood the chamber with mist to where u can even see whats in it and the gauge will read about 65. the cool mist will spit barly visable mist into the chamber and the gauge will read about 65 also. so i put the gauge (digital)out side and it read what the weather chanel says within 1%. so what should i do this will be the 3rd one now that r always low so i think mabys its me but i cant see how it aint reading 85 or so especally when i see that ultrasonics mist. u did read some where to just put ur coolmist(spinner kind) in the chamber and leave it on all the time. whats do u think i should do hippie? is there a way to say from experince an "ultra sonic 3 times a day for 20 min a time is good enough" or "putting the coolmist and run it 24/7 is good enough" cuz something aint right here and i need to fix it right away i need 90% or better like yesterday!

It sounds like you have at least 90% in there. Don't trust cheap hygrometers. Lots of digital ones will work fine in the 10-60 percent range, but can't handle the high humidities in your chamber. Torka.com has some good hair hygrometers, but be warned: Mount it well, cause if you drop it, the thing is toast.

i dropped my first one proly 20 times before it finally crapped out after 3 years but yeah, treat it like the delicate scientific instrument that it is.
don't put the humidifier directly in the chamber as is, that will give too much condensation. you need to run it thru a long tube to first catch the droplets before it enters the chamber.
and get a timer and a good hygrometer and you can fine-tune your chamber to the right humidity.
right now i'd run it like 5-10 minutes every 6 hours or so, until you get a hygrometer and check it out right.

well this is what im gona do shroom gods humi. tek from the shroomery says to loop a garden hose a few times and hook it up to the cool mist and he says u can run it 24/7 and that will provide my air exchange also. what do u guys think about that one? the hole point in useing a coolmist w/ looped hose is to limit the water droplets on the surface of the substrate right? about those water droplets is it ideal to have a little bit on the surface or should there be none on it?

You want humidity, not standing water. The hose idea works fine, but expect to spend a few days tuning it. If it's too short, you will splatter water everywhere. If it's too long, dry air will come out the other end. Don't set the humidifier on the floor. 90% of all contams are within 1 foot of the floor. You don't want to suck up all that contamination and blow it into your grow area.

none.
i think 24/7 is too much with a cool mist, you'll want a timer.
