Misting by hand or ultra sonic mister? Hygrometer Q
    #9091725 - 10/17/08 01:38 PM (16 years, 3 months ago)

I have a cluster of jars incubating at the moment and when they are ready i want to be absolutely sure that i have the correct materials for fruiting them in a tray. I have a 10 gallon aquarium which i will be using perlite at the bottom with the tray being suspended a couple of inches above it. I have a hose connector on top of the lid of the aquarium in which i plan to use a ultrasonic fogger connected to the aquarium by hose. Ive heard a lot of talk on the forums where people say you should use a ultrasonic fogger instead of manually misting it and the other way around too. I would like to know what is the final truth to this because im confused to which side i should take. Your input is greatly appreciated.

One more thing i have a Holmes digital hygrometer $20

http://www.bedbathandbeyond.com/product.asp?order_num=-1&SKU=14216596

to measure the temp and humidity. Is this a sufficient enough for a hygrometer? I havent tested it yet. It allows you to calibrate it once you get it but dont know if i need to do RRs way of wrapping it in a towel or whatever. Ive read many comments about inaccuracy of certain ones and would like to know the best one for the job keep in mind im not going out and buying a $100 dollar or more state of the art hygrometer. Try to keep it inexpensive and very accurate.

Again your input is greatly appreciated thank you

Bumping because its off "page" or not on first page will likely get you in trouble. I do believe its ok to bump if its been more than a day. I know myself I go back 3-4 pages of "updated/new" threads.

Look at that product, I don't see where it says it can be calibrated. I would just get an analog one that can be calibrated from a cigar shop :smile:

I set up my fruiting chamber like this and gave it a test run and it worked perfectly.

1 dual output air pump

Both hoses run into a little positive pressure zone and are submerged under water along with the ultrasonic mister. Then there is one line of hose that runs out of the top of the pressure box and into the top of the fruiting chamber. With my digital hygrometer I had 99% humidity for the week I had it setup and running.

My fruiting chamber is basically a double tub with the one on top being taller than the one on bottom.

I wonder how my brf cakes would do spawned to coir in the bottom tub.

My friend relied on just an ultrasonic fogger for a while, until he realized his hygrometer was lying to him and his cakes were completely dry.

Misting works fine.  If you have a fogger, use it, but you should still mist anyways.  Don't go running out to buy one if you don't have it yet though.

I smoke cigars and this is how we callibrate our hydrometers. Place it in a zip lock bag. take a beer cap full of salt and place several drops of water until is appers to be wet like beach sand. Place the wet salt in the bag and seal. the salt will onlt allow the water to evaporate a 70% humity. so you can tell how closes your hydrometer is.
Try it.

The salt tek is not applicable for mushroom use.  Hygrometers are only accurate through a narrow range of ten to twenty percent.  If you calibrate a hygrometer at 70%, it won't be accurate below 60% or above 80%.  Calibration at 99% after wrapping in a damp towel for an hour is what you want for our use.

Don't depend on a humidifier to do your misting.  Proper misting requires a human touch. 

Don't bump your own threads without waiting at least 24 hours.  Next time, it gets locked.

Sounds Good,

Sorry I gave the wrong advise, I was not trying to mess anyone up. If you smoke stinky cigars, this will help you calibrate your hydrometer for your humidor. Hey RR does it become more difficult to calibrate the small percentages as you increase into the highest range of RH? Is the difference between cailbration range for 1 percent humity differnt at certain sturations ? If their is no significat difference (less than 5% difference) how would this effect calibration?

It's a huge difference.  If I calibrate at 99%, the hygrometer won't read below 65%, even if I put it outside in the desert when the ambient is less than 10%.  That's why it's important to calibrate at the range you're going to be monitoring. 

I also have a humidor for my cubans and use the salt tek for it.

sorry that was not what I asked. if you had a jar with 70 marbles of humity, Is there a difference (Size or structure)to the humity marbles at a diffeerent amounts. If the marbles are the same than adding one marble (percent)when the is 70% should change the it the same amout as adding one marble at 90 %. Do you get my question now?
I like those cigars too. I like: Cohibas, Punch, romeo y juliet, and CAO Mx2. to name a few.

Here look at it this way. I work as a cook and we calibrate our cooking therometer in a glas of ice water to 32 degree F. this can then be used to judge temps 150 degree above this. And this is recomended practice by state  health inspectors. They belive this to be accurate enough. how this differnt than humity calibrations. If one percent humity is the not the same as 100 percent. this is common sence. The idea is to get a reference point. It would only make a difference if the rate of change was not constant. dose this clear up my question? I am Zool major and want to make sure I can tust your advise. Not trying you bug you. I save that for my professors.

sry didnt know bumpin was a bad thing here, read multiple times people doing so because of that same thing so i only followed what everyone else was doing lol..but yeh wont happen again. So with the calibrating the the digital hygrometer i put it in a damp towel for an hour then hit the calibration button and its done? Sry if i dont follow, thanks again

you so you all get the point of my post. If their is no sig rate of difference, than you can calibrate it to 70 and it should work. And my adives sould have not been shot down so fast, and by a Mod. Or just show me your proof of the rate of change. how it changes at higher levels. if the window is only 20 % it must be a high rate to me. If your adives to people is that good advise is wrong. than I would have a harder time trusting you. I see this done here before. I have to deal with the professors egos at school. I would not like to deal with that here. Trying to calibrate my shroometer! your are all great just for being here trying to help.

It's based on experience.  Analog hygrometers have a hair inside that changes length as the humidity changes.  The change in length operates against a spring which drives the needle.  It's only accurate through a narrow range, not the whole 0 to 100 that is printed on the dials.  You want to calibrate in the narrow range you operate at, which in the case of a fruiting chamber is near 100%, thus the damp towel gets you very close.

For a humidor, the salt tek works perfect, and the damp towel would not be a good reference to use, since you don't run a humidor at 99%.  That's my point.

I also like Cohiba.  They and Monte Cristo are my favorites.

Sounds good,

My Lab professors called me the devils advocate. It is actually a great teaching method and a great way for people to learn something out of their confort zone. Thats what makes this hobby so fun. When play devils advocate you must be well informed to take the oppsite side from views of the group.If succesfull everyone should learn more in the end. I enjoy those cigars too. My friend was a chef at a hooka bar, so i bought on from the owner. Great alt. for this time of year when it gets cold and you have to spend an hour int he cold (depending on the ring gage, I perfer the larger ones witha big ash so it burns at a lowere temp and release less or the nasty flavors). The hooka I burn inside and smells alot better that the cigars. I the end I think there is nothing better than good draw Mon.
Sorry for going so off topic with this one. Just want to explain there's method to this madness.
