Hygrometer

Spark · 03-11-05, 13:03

My meter is very sketchy.
Often times it will read but it's not 100% accurate.
There are two setting of which are IN and OUT

OUT=94.5
IN= 76.6
Currenty

I'm using this to incubate some jars
what is the actual tempeture inside
the box?

03-11-05, 15:13

Nobody can tell you that. Hygrometers are for measuring humidity, not temperature.

cutty · 03-11-05, 16:11

Personnally I dont incubate jars.I find it works juat as well to leave em at room temp (70-75 degrees),Its much easier.RR is right with what he said about the hygrometer.A hygrometer is used more for your grow chameber not your incubater.Use a tempature gauge.

03-11-05, 16:35

Hygrometer is for humidity and thermometer is for temps. If ya have an outside and inside setting the outside temp is recorded by a sensor that is outdoors or inside the chamber. If ya want to record the temp as "inside" then put the entire instrument in your chamber and that will show up as the "inside" temp.

Spark · 03-11-05, 17:03

Well the humidity reads 20% no matter what i do.

03-11-05, 17:06

The humidity sensor is probably on the part of the deviced that is outside your chamber. Stick the whole thing in your chamber and see what it reads. Is it digital?

03-11-05, 17:23

You can get a good hygrometer at www.torka.com

Spark · 03-11-05, 17:28

It is digital...

And since it reads this way it would be counterproductive if i had it inside cause then i won't be able to tell where the temperature is at.

Grab a cheap temp gauge and Hygrometer at wally's world its about 10 bucks and throw em both inside your bin,then you wont have all the digital probs.

destroy_erase_improve · 03-12-05, 00:03

a foaf had a semi cheap one he got from walmart, it sucked ass, it would get to about 85% and never rise above it, he then went to a cigar shop and got a nice digital one for about 20 bucks. it served him really well.

Raptor · 03-15-05, 15:56

Actually it wouldn't be counterproductive, I have an identical hygro/thermometer from radioshack. There's a node on a long cable, this reads as the outside temperature. The unit itself reads (indoor) temperature and humidity. If you want to know "where the temperature is"; it's wherever you place the unit itself. Mine, under the digital display, has small holes (looks like speaker holes or something), that's where the indoor temp/hum. instrument is. I keep the unit resting at the bottom and the node taped to the upper side of the box to get the temperature for both bottom and top of the box.

03-15-05, 16:59

You should be able to see inside your grow chamber. If you can't make it to where you can, otherwise it will be dark in there all the time and that is no good.

the_other_chap · 03-15-05, 17:30

How accurate are digital hygrometers?
What type of sensor do they use?

I used to have a cheap "horse hair" type that I kept in the terrarium, but it never seemed very accurate, so I don't bother anymore.
Incidentally, if anyone needs a hydrometer calibration method (must be one in the archives, but I've bookmarked this one):
http://www.dukecitycigars.com/hygrometer.htm

Raptor · 03-16-05, 15:37

I guess they're a lot more acurate than analog ones, but I don't know specs. This is the exact one I have
http://www.radioshack.com/product.as...5Fid=63%2D1032

On manual it says Relative Humidity Operating Range is 25% to 95% RH. sooo?

drgonzo1969 · 11-10-05, 19:02

I just bought a analogue hygrometer from a cigar shop. It is plastic and does not feel very sturdy. Will this be a problem? Also, the thing cost me $10, are hygrometers around that price range usually accurate?

mwillis71 · 11-10-05, 19:51

I would get a good digi one from radioshack. A foaf has noticed that the small plastic ones aren't very acurate with usually a 10 to 15 percent fluctuation.

11-10-05, 20:13

I prefer the cheap analog ones like that from a cigar shop. Wrap it up in a damp bath towel for half an hour. Unwrap it and adjust the recessed screw on the back until the dial reads 98%. That's the beauty of those analog hygrometers. You can calibrate them and they'll be very accurate. The hair or other fiber inside stretches with time, so re-calibrate it again every two weeks or so.

mwillis71 · 11-10-05, 20:18

Well shit, no wonder the one my buddy had didn't work! Thanks for the info Rodger. By the way, the ones that you get from radioshack have a remote so you can put one on your wall to read your temp and humidity in the house and it then has a offspring that you can put in your chamber and it will be readable from the parent on your wall. The beauty is that you can check up on your babies anytime without having to open the fruiting chamber and bothering them or possibly contaming.

Dank Side Of The Shroom · 11-10-05, 20:18

I've foudn cheap plastic ones are always off at least 10%. I paid 300 bucks for a state of the art digi, But thats because i saved up for a while to get it. Any ways any digi will be reliable as well as others but try to avoid the cheapies.

drgonzo1969 · 11-11-05, 00:35

thanks for the help. I am gonna try the wet towl trick tomorow.

11-11-05, 10:45

I bought one prolly exactly like yours for about $9 and it works great. It works much better than any digital one I could afford. Most of the digital ones simply display the word "high" after they reach 90%. That is not good.

anticheffy · 11-11-05, 13:56

For about 100.00 you can get a digital psychrometer at an HVAC supply house that works accuratly for along time, mine is years old and still checks out when readings are compared to $100,000.00 environmental monitoring equipment.
Mine gives wet bulb and dry bulb temp, humidity, dew point, enthalpy and some other things.

Hi

My foaf thinks alot of her problems are because of humidity. She is going to get a decent Hygrometer soon but has already had to send one back as it would not read over 80% ( from the ONLY cigar store in NZ).

She is willing to spend some money to get something that will work. Her options are:

Ship a decent one (the polytherm from the arcives) from overseas
Ask to trade (not that she has alot ... A single GT sporeprint taken in a glove box)... long shot but some one might have a spare around??
or get a digital one from the local jay car ( our radio shack). Will it servive the with all the water in the air? will it short out the unit over time?

thanks
jestah

InfectedMushroom420 · 01-12-06, 07:36

Hi Jestah,

I can tell you by experience that the radio shack digitals can not stand up in the high humidity. I tried one and after it got over 90% or more the entire liquid crystal display screwed up then didn't display at all. After drying it out with a hair dryer, it worked again and I saved it.

What kind of problems is your friend experiencing she believes are due to humidity?
It would also be good to describe her set up and daily care/operations so others here can better help determine and suggest a solution(s).

01-12-06, 07:50

You want a mechanical hygrometer from a cigar shop. They must be calibrated. You can't expect to take it out of the package and have it be accurate. The one you had was probably ok. See if they have another.
RR

mushit · 01-12-06, 11:02

Yup. Most of them are not very accurate but will give a good indication of RH. I bought mine online from a pet shop. Works great. Cost about $10.00 delivered to my door.

Omega 11 · 01-12-06, 12:11

whatever you do, don't buy the digital hygrometer from radio shack! I had one of those things in my terrarium, constantly reading 98%, until I bought one from a tobacco shop and compared. I found out that my terrarium was at 90% and the digital was broken. In fact, after I took the digi out, it still read 98% in the house. I'm guessing the long exposure to moisture broke it, which is lame because it's supposed to read humidity, or it was janky to begin with. I'd go with rodger's advice, cigar shop hygrometer, they're a little larger than a quarter, cost under $20. Mine has worked fine ever since I bought it.

Hippie3 · 01-12-06, 12:13

get the polytherm, in my opinion.
mechanical synthetic fiber
get two so you can compare readings

jestah · 01-12-06, 15:07

I think i will go for the polytherm as i have called around NZ and have had no luck finding anything.... The one she got from the only cigar supplyer in Nz would not read over 80% even when covered with a hot damp cloth. I have sent it back.

Her set up is : a 60L (15.8gallon) plastic bin the sides painted black (on the outside of the bin) with 3 inches of grow rocks in the bottom and 2 inches of water. A small air stone and fish tank heater are under the waterline and bubble away soon after she wakes up to just befor she goes to bed. She also puts a light above the bin for around 12 hours per day. temps in the bin range from 70-84f (hard to keep stable thinking about trying to insulate but moving flats soon) room temps are around 60-70f (more often in the lowere part of that) She suspects its this large difference that is causing alot of condensaton on the lid and walls... not high humidity. Her cakes seem to dry out and give small fruit. She also had a lot of aborts in the 2nd flush as she was misting and didnt do a decent job and porbibly put a lot of water drops on the new pins. The fruit also tend to open very early.

She has also found a 7w fluro lamp. Its quite dull but will this be enough to get cakes to pinn well? she had good pinning when using a 20w energy saver, equivilant to a 100w incandesant.

thanks for the help it is gratly apprecated

mushit · 01-12-06, 17:00

The water droplets on the walls are caused by a temperature differential from the inside to the outside of the chamber and the RH being higher inside. Chances are if you have water droplets condensing on the inside of the chamber, the humidity is fine. No need for a hygrometer.

Perlite will work a lot better than grow rocks. Also try not to have too much standing water in the perlite. This gives more surface area for evapouration from the perlite.

As far as lighting goes, all you need is a bit of ambient light to initiate pinning. A clear cover and leave the lights on in the room for a bit.

jestah · 01-12-06, 18:01

Found this... has any one used this? should be ok or should she spend the extra cash and get the polytherm?

cheshire · 01-31-07, 13:13

hey there, got a really nice thermometer/hygrometer today, digital one that looks decent and isnt too big for about $50

was wondering if any1 could link me to that post in which u check ur hygrometers accuracy, i cant find it?
has summin to do with putting salt in a tin with the hygrometer?

btw got it after all places at a cigar store cuz i heard sum1 mention it, was in the first store of its kind i had to look

spent hours looking for a normal therm and didnt see one proper one

so if u looking, go to cigar store and get a sweet combo

boots420 · 01-31-07, 13:44

heres a way to calibrate you hygrometer as well as test it.
>> calibrate <<
Here's the procedure you should use:

Get a bottle cap of some sort - like the kind you might get off of a beer! Fill it with regular ole' table salt. Then drop a few drops of water on the salt. DO NOT put to much water on the salt. The salt should only be damp, and not a liquid solution. It should be like moist sand, not like soft mud.

Then put the bottle cap of salt and your hygrometer in a see-through, sealable container. I like to use a large freezer bag. Seal the freezer bag or other container. Wait several hours (about six). The humidity inside the bag will be 75%. Compare it to your hygrometer. You will then know exactly how far off your hygrometer is.

golly · 01-31-07, 14:15

And for the high end [100%] Soak a folded paper towel in warm water and
put in a ziplock with yer hygrometer ..Seal the bag and wait an hour to get your reading...Make sure no water touches the sensing element...
It should read 100...
Its often easier to just make the correction in your head for minor deviations
than it is to adjust the calibration screw...

On mine when it reads 97% - it is really 100...

Boombloom · 01-31-07, 15:00

With a digital accuracy is gonna be pretty good. Check out this one, its a pen sensor, you can cut a small hole in you terrerium to poke the sensor thru and leave it covered with tape when not in use. Its $68 available here.

cheshire · 01-31-07, 15:39

should i leave this hygrometer in the fruiting chamber all the time or just when im checking..

spose leaving it in all the time with high humidity would only affect its life span no?

cheshire · 01-31-07, 15:45

oh and hygrometers been in with salt for about 2 hours now and its at 74% so seems good

yay

Boombloom · 01-31-07, 16:04

if its for a cigar box you can prolly leave it in. can we have pics?

cheshire · 01-31-07, 16:25

im actually having a problem with getting photos on my computer but luckily here is the exact same one in white that i found on google images

hyd08_200_p1.jpg

not bad eh

cheshire · 02-01-07, 03:24

yay, leveled off at 75% after being in there for a while, perfect readin

boots420 · 02-02-07, 10:00

as for leaving the hygrometer in the fc. i have found that the inexpensive digital ones are not made to handle being in such a high rh environment. wires start to corrode, the pcb get water logged and the the gauge craps out. if you wanna leave it in there either get a digital one made to handle the high rh....(expensive) or get a good analog one from a cigar shop.....(cheap).

Hippie3 · 02-02-07, 10:29

i would not leave it in the chamber for extended times,
everyone i tried that with
crapped out fast.
better just to check regularly
then once you get it zero'd in
you won't need to as much.

hungryhippo · 02-27-08, 10:47

I went to the only 2 cigar shops in town trying to find a polytherm hygrometer like Hippie3 suggests, but they dont even have anything close. The only hygrometer they have with a needle is NON-adjustable cheap $5 model that when I exhaled my breath into in the needle didnt budge. I dont remember the brand but they had 2 types of digital hygrometers that "claim to be within 1% accurate." One was $30 and the other was $40. Will this work, or would I be best looking for the other type? Does anybody have a link they can post up to a good reliable hygrometer I can get? Or maybe ebay or something.... Or will the digital work?

dial8 · 02-27-08, 10:53

Those will probably work. Some digis will only read "high" when the rH is above 90% so thats really no good. Make sure these dont do that.

Lazlo · 02-27-08, 11:18

I've bought a few analog ones from these guys and they were ok and the shipping was incredibly fast. I now get the analogs at Lowes for 4-5 dollars. It's an Accurite thermo/hygro combo that works ok and holds the correct rh after it has been calibrated.

Everyone is raving about this digital model. Cigar guys are really anal about hygrometers as you may know. The reviews for this model are great, so i'd be inclined to purchase it. I prolly will when I need a new hygro.

solentblu · 02-27-08, 18:39

most of the cheap digitals work ok but dont leave them in extreme humidity for too long.more than a few hours.they are not sealed to well and short out.at leased thats been my experience.

Doctor D · 02-27-08, 19:24

I bought the most expensive cheapie at Lowes, probably around $30. When I'm at 100% humidity, it will register 98% RH. IMO, this is fine for our purposes, especially for cakes. Regardless of its accuracy in reporting the actual percentage of relative humidity, it makes an excellent gauge of changes in humidity. So if your cheapie hygro all of a sudden drops low or shoots higher, you know there's something amiss that you need to look into.

Do you happen to remember the brand? If not I can just look for the digital around $30. thanks

I had one of those things in my terrarium, constantly reading 98%, until I bought one from a tobacco shop and compared. I found out that my terrarium was at 90% and the digital was broken. In fact, after I took the digi out, it still read 98% in the house. I'm guessing the long exposure to moisture broke it, which is lame because it's supposed to read humidity, or it was janky to begin with. I'd go with rodger's advice, cigar shop hygrometer, they're a little larger than a quarter, cost under $20. Mine has worked fine ever since I bought it.

jestah Mycophiliac Join Date: Nov 2005 Posts: 80	thank for the advice I think i will go for the polytherm as i have called around NZ and have had no luck finding anything.... The one she got from the only cigar supplyer in Nz would not read over 80% even when covered with a hot damp cloth. I have sent it back. Her set up is : a 60L (15.8gallon) plastic bin the sides painted black (on the outside of the bin) with 3 inches of grow rocks in the bottom and 2 inches of water. A small air stone and fish tank heater are under the waterline and bubble away soon after she wakes up to just befor she goes to bed. She also puts a light above the bin for around 12 hours per day. temps in the bin range from 70-84f (hard to keep stable thinking about trying to insulate but moving flats soon) room temps are around 60-70f (more often in the lowere part of that) She suspects its this large difference that is causing alot of condensaton on the lid and walls... not high humidity. Her cakes seem to dry out and give small fruit. She also had a lot of aborts in the 2nd flush as she was misting and didnt do a decent job and porbibly put a lot of water drops on the new pins. The fruit also tend to open very early. She has also found a 7w fluro lamp. Its quite dull but will this be enough to get cakes to pinn well? she had good pinning when using a 20w energy saver, equivilant to a 100w incandesant. thanks for the help it is gratly apprecated

Chances are if you have water droplets condensing on the inside of the chamber, the humidity is fine. No need for a hygrometer. Perlite will work a lot better than grow rocks. Also try not to have too much standing water in the perlite. This gives more surface area for evapouration from the perlite. As far as lighting goes, all you need is a bit of ambient light to initiate pinning. A clear cover and leave the lights on in the room for a bit. __________________ Up to my elbows in SHIT

Fill it with regular ole' table salt. Then drop a few drops of water on the salt. DO NOT put to much water on the salt. The salt should only be damp, and not a liquid solution. It should be like moist sand, not like soft mud. Then put the bottle cap of salt and your hygrometer in a see-through, sealable container. I like to use a large freezer bag. Seal the freezer bag or other container. Wait several hours (about six). The humidity inside the bag will be 75%. Compare it to your hygrometer. You will then know exactly how far off your hygrometer is. __________________ I live life like the captain of a sinking ship................. Last edited by Hippie3; 02-02-07 at 10:30.

golly modapotato Join Date: Oct 2005 Posts: 6,198	And for the high end [100%] Soak a folded paper towel in warm water and put in a ziplock with yer hygrometer ..Seal the bag and wait an hour to get your reading...Make sure no water touches the sensing element... It should read 100... Its often easier to just make the correction in your head for minor deviations than it is to adjust the calibration screw... On mine when it reads 97% - it is really 100...
