Perlite - terrarium - condensation
    #386079 - 09/05/01 02:54 AM (23 years, 9 months ago)

My friend has a terrarium (aquarium) were he put his casings, he uses perlite for humidification. Now, he can barely see any condensation on te walls of the terrarium but the hygrometer (analogic) reads 95%Rh, temperature is arround 80?F. Is there any problem with the lack of condensation on the terrarium walls ? Does it mean the hygrometer is messed up and humidity is much lower ? His casing top layer is moist and mycellium is spreading slowlly.
This 3rd. person stuff is weird.

BTW, the aquarium lid is not air tight and has two holes (2cmx2cm), one on each side of the lid that were used to insert the tubes, this holes are closed but not air tight also.

Peace,
MAIA

If you use perlite you should have enough humidity.
To calibrate your analog hygrometer:

Sensor calibration should be checked at 2 points. We use 33% and 75% at the factory. Never use 100% as a calibration point. One of our competitors suggests testing their calibration at 100% using saturated air. This is not accurate for the simple reason that most all humidity recorders limit the top reading to 100% If your instrument is reading 10% high, it will still look good at 100% due to the instrument's ceiling.
The only practical way to accurately check your RH calibration is to use known humidity standards. You can create your own standards using saturated salt solutions in a closed container. Different types of salt can be mixed with distilled water to form saturated solutions having a fixed RH at a given temperature. The following table shows the RH of various salts solutions at room temperature (68 F).

Lithium Chloride 11%
Magnesium Chloride 33%
Magnesium Nitrate 54%
Sodium Chloride 75%
Potassium Chloride 85%

Accurate results are possible with a little care. Please follow these guidelines:
a.) Use only pure water and salts. Do Not use common iodized salt for sodium chloride.
b.) The calibration must be done in an airtight container. If you're calibrating an RH-52 with an internal sensor you must make provisions to suspend the instrument above the solution. The sensor should be close to the solution, but avoid getting the solution on the sensor or instrument. Watch out for splashing if moving the container!
c.) The sealed, airtight container needs plenty of time to equilibrate. You should allow at least 8 hours, 24 is better. The key to faster equilibration is to have a small air volume and a large solution surface area. Some Tupperware containers work well, but be sure they're truly airtight.
d.) The RH values assume a constant temperature.

When making up the solution, slowly mix the distilled water and salt until a saturated solution is obtained. Make sure there's an excess of salt. Handle all these salts and solutions with care!

http://www.switchedon.com.au/RH_sensing.htm

Analog (dial-type) hygrometers are often shipped from the factory out of spec. To calibrate, you need plain table salt, a few drops of water and a see-through Tupperware container with a tightly fitting lid.
Place about 1 teaspoon of salt in a small shallow open container, such as the cap to a jar. Add a few drops of water to the salt. You DO NOT want a solution or to dissolve the salt, only get it damp. Place the container with the salt solution in the Tupperware container. Next, place the hygrometer in the Tupperware container face down. This will allow you to view and check the reading of the hygrometer before you open the container. CAUTION - do not spill any salt or solution on your hygrometer! Place the lid on the Tupperware container making sure it fits tight. Allow to stabilize for at least 6 hours. Without opening the container, check your reading. It should read exactly 75%. If not, note the deviation and or adjust the hygrometer

Well you guys are right, yet I have used perilite for a couple of years now and never found the need to calibrate or even take a simple humidity reading. If your using perilite properly you will have enough humidity period. To explain why there is no humidity on the walls of the terrium, you need to think back to your Earth Science class days. Remember cold air holds less humidity, while warmer air can hold more moisture.

When using perilite and you see moisture on the sides of terrium, I would quess the temperature is in the mid to low seventies. The air inside the terrium cannot handle all of the humidity the perilite pumps into the air, thus it condnenses, yet your humidity level is still well around 90%. As soon you get the temps up into the eighties the air inside the terrium can accept the moisture and the moisture off the sides dissapears.

If you want to prove to yourself that there is in fact moisutre in the air inside your terrium without spending any money do the following. Fill a zip lock bag with ice and set it on the lid of the terrium. Within 10 minutes the spot on the lid will cool down and the moisutre inside the terriium will condense on that spot. When you lift the lid, there will be moisture droplets where the ice made the lid cold. Good Luck

Yes, Fonz, condensation is an indication of dewpoint, not humidity.

tried a few hygrometers now, ranging from cheap to (what i think anyway) expensive, all been worthless, and waste of time. Best way to tell, experiance, experiment see what works. It isn't exaclty rocket science. Only a scum newbie grower myself and i can tell whether there needs to be abit more moisture or bit less in my terraium.

Quite so, aenima. You can grow perfectly fine shrooms without a hygrometer.

>The air inside the terrium cannot handle all of the humidity
>the perilite pumps into the air, thus it condnenses...
If the air "terrium cannot handle all of the humidity" then it?s saturated with water, thus the relative humidity is 100%.

But to say "cold air holds less humidity" is wrong anyway.

Anno, That is an excellant website. I can't wait to read more. I did use a very popular and techanically incorrect and overgenerlized theory to explain what was going on. Thanks for getting the correct info out there!!!
