|Too much humidity?! help me folks||11||02/10 08:48pm||chummy|

I would like to know, i have a new terrerium right now (rubbermaid container) with wet perlite on the bottom, and a cool mist humidifier attached to it. The temperature is a consistant 70-75 degrees, and around 90% humidity. I want to make sure i have the chamber working properly before i put the cakes in it.
There is a tight seal with weather stripping around the edge, 2 hoses going into the chamber out of the humidifier, wet perlite covering the bottom of the container.
Should I also use a light? the chamber is clear, i might just get a cheap lamp, cut a hole in the top, and put a piece of plexiglass on it. Thanks for the help!

As long as there is ambient light getting into the chamber in addition to your humidification system, that's all you need. You do not really need a Humidifier with Perlite, but some people do use them. Be sure you have a timer or things can get too wet.

well, is the temp and humidity ok?
|By Nan (Nanook) on Thursday, October 25, 2001 - 11:30 pm:|
I doubt your humidity meter is accurate unless you spent at $$ on a scientific grade single purpose instrument. Perlite is sufficient all by itself, with the humidifier I am sure it is fine. As long as there is condensation on the grow chamber walls, your humidity is pretty good usually.
Fruting temps work best for me between 75*F and 82*F but they will fruit fine at 70*F, just a bit slower that's all.
Humidity for cakes should be as close to 100% as possible. Be sure to keep the Double-end Casing moist.
For casings they like things a little drier... 85-90% Humidity works fine here with an occasional Misting of the casing surface.

sweet, the temp is actually warmer than i said
its between 75 and 80
and the humidity is stable
thanks for the help
the perlite keeps it stable when i open the lid
Now all i have to worry about is light, i don't know what i should use, any hints?
the cakes are almost ready (within a week)

A have not been able to find a humidity meter either digital or analog that will work in the 90-95% range. In quotes' 9er tek he said to keep it at around 92 and shows a picture with fogged glass that is maybe too much humidity. I'm pinning now through the casing and am wondering what to do.

Keep the humidity high and fan more often.

Okay I have a rather large terrarium going for my PF style tek cakes. I just picked up a digital guage that measures temp and humidity... Just for kicks i put the sensor in the terrarium to see the humidity level and it read 45% and that was 30seconds after spraying vigorously(spelling) ....... I was under the impression the level had to be around 95% how in the world am I going to get it up to that level?
|By Snoopy (Snoopy) on Friday, October 19, 2001 - 08:44 pm:|
BTW: it should be important to mention that I just put perlite in the terrarium at the same time i first put the sensor in.... bought them both at wal-m**t....
|By Nan (Nanook) on Friday, October 19, 2001 - 09:16 pm:|
Unless you buy a scientific grade instrument you cannot trust your humidity meter. My trust begins to grow as the price goes over $100 for a single purpose RH meter. At the high humidity levels produced in a grow chamber the Wally Mart instrument is notoriously inaccurate. Sorry, if you had asked I may have could saved ya some bucks. You may even want to get your money back.
An old cheap thermometer is really all you need unless you have money to burn. Me... Go Cheap.
|By Snoopy (Snoopy) on Friday, October 19, 2001 - 09:20 pm:|
Okay the money doesn't bother me as much as thinking that my humidity level is to low... *good thing or bad thing* Yah the digital temp/RH deal cost me just $15bux perhaps the digital reader for the temp will make it worth while, I just put a layer of perlite and soaked it well, and have my cakes on their lids. Already condensation has built up on the walls so I guess thats good enough thanks Nan.
|By Nan (Nanook) on Friday, October 19, 2001 - 11:06 pm:|
Ya, all you have to do now is fan a few times a day and mist when the condensation on the walls dries or recedes. Make sure the verm casings are very damp.

Snoopy, 45% humidity is below normal. It must be broken. What does it read in other areas, like in your house or outside?
|By Hatcher (Hatcher) on Saturday, October 20, 2001 - 09:21 am:|
Snoopy, I too desire accurate humidity readings. For whatever it's worth, but how can we know if we can't read it? Best I can tell our best bet is Oregon Scientific. Just go to search, they sell direct, but can be found a few bucks cheaper. Nan is right in not trusting anything less than something atempting precision for a hygrometer. These might work, and they're wireless..gonna be around $70 for one unit, a bill give or take for two. Gonna take reading two units at once to guage accuracy though Snoop..on my wish list, ya get the temp too of course..

to test the accuracy of your hygrometer-http://www.shroomery.org/findorgrowthem/calibrateyourhygrometer.html
this method will tell you how far off your hygrometer is... then you can re-calibrate it yourself if yours is analog, or simply determine "how far off" it is and add/subtract the difference (id only recommend this if your hygro. is only a few degrees off, not several. it works for hygro's that are not properly calibrated but work- they dont fix non-working hygros).
casings should be at 85-92% rh during cropping mode. (TMC)

After seeing the hard earned money I must spend on a Rh meter I've decided to go with "shroom intuition". I'm actively watching you all for feedback on your results from purchases of top end meters.
|By Brettiejams (Brettiejams) on Saturday, October 20, 2001 - 05:23 pm:|
"shroom intuition" is all you really need.
It's usually new people who think they need a fancy
RH meter..... I did when I was new.
Once you taste some success without one you tend to realize those little do-dads are unneccessary and somewhat frivolous.
If you've got money to burn they can't hurt anything though
|By greenthumb (Greenthumb) on Saturday, October 20, 2001 - 08:32 pm:|
They can hurt the old checkbook!

Nue and Bret are right, we don't need 'em, we just want 'em!

I am useing a low-cost tek since I only have two jars ready to birth right now. If I were to use a ice-cream bucket as my humidification chamber with about 1 and 1/2 inches to 2 inches of perlite + h202/water, how long can I expect it to raise to a good, 90-95% humidity. I am wondering how long before I birth to make it. Also, my cakes are 100% -- should I birth or wait for invitro pins? Whats the difference? They are GC from 3Mshroom.
|By Nan (Nanook) on Friday, October 19, 2001 - 08:34 pm:|
As long as you Mist daily Perlite will maintain humidity all the way through the flush.
|By SYDYSTYK (Addict) on Friday, October 19, 2001 - 10:18 pm:|
i wouldnt wait on pins- i have jars that are a couple months old- still no pins- for me invitro pinning is a rarity, i would wait one week after complete colonization

I have a 58 qt sterlite terrarium with perlite for humidity. I have a piece of wheather stripping all the way around the top of the terr to keep humidity in. I spray down the walls at least twice a day. The problem is after i spray the walls they are dry again in just a few hours. So i was wondering what some of you guys/gals do to keep the humid high and not loose so much humid? Thanks for the help.

use more damp perlite above the water level.
|By Jesseb (Jesseb) on Tuesday, December 18, 2001 - 02:39 am:|
I have two inches of perlite with no standing water. I was wondering more along the lines of how to make a better seal on the lid and the terrarium. Should I put more perlite in? thanks Quote

another option is a bubbler...
