Condensation, the real indicator?
    #559587 - 02/22/02 12:50 PM (14 years, 9 months ago)

Ok, Im doing 6 casings, they dont all fit in one chamber so I have 2.
Both chambers have perlite for humidity. One chamber (a shelf lower) has alot of condensation buildup but no hydrometer, im confident by the condensation that the humidity is very high, and thats what I want.
The second chamber (one shelf up) has a digital hydrometer and it reads 95-99% constantly. What gets to me is that theres no condensation what so ever. It makes me paranoid that theres not enough moisture.
The outside temp for the top chamber is 69-71degrees, and Im measuring the bottom one as I type here...ok its 65ish.
Should I not worry about all this and just blame it on the extra 3 degree outer temp that eliminates condensatin?
Thanks all!

Those digital hydrometers suck... well, at least the one I had sucked. I bet if you take it out of the chamber and let it sit in a dry area for a day it will still read 95-99%. I had one that I got at radio shack and it would get stuck in the high humidity range for some reason. I would have to pop the battery out to get it to reset. If it turns out that yours acts like mine did, you can get a good analog meter from a cigar shop faily cheap.

my friend got his hygrometer at wallys, it was like 14 bucks, i know that they are not 100% accurate, but it seems to work excellent. its a springfield model #91048-w. good luck and keep us posted! an update on this hygrometer, i beleive it is working quite well, if my friend leaves the lid ajar, the humidity drops down between 80 and 85, depending on how far he has the lid ajar. it seems to work better than the radio shack hygrometers that everyone says are inaccurate. like i said, i dont believe it to be 100% accurate, but it seems to adjust accordingly.

Well the hydrometer is a pretty good one, I take it out and it goes down right away. And when I open the lid it goes down like 3-4%. Its seems ok to me. My model is a Bionare Hydrometer/temp guage, a pretty reputable brand.
Im gonna switch the chambers around and see if they switch in condensation % as well...thanks

my radioshack hydrometer works exelent! One of my fruiting chamber has a piece of plexiglas for a lid, when I slide the lid over and leave about 2in of the terrarium open, the humidity drops to 85% or so. By spraying the walls of the chamber it rises again. If you have a fruiting chamber full of perlite, your humidity most likely really IS that high. Perlite always works, so its not like your humidity is that low. You dont have to have condinsation to have high humidity. If you have casings i would recomend putting them in a terrarium without perlte, casings provide alot of thier own humidity. With no perlite you can regulate the humidity levels by spraying the walls. The radioshack hydro/thermometers are great units, I dont care what anybody says.

Condensation indicates dewpoint, not humidity.

Yes dewpoint....I posted a dewpoint thread 2 days ago and was told that 70degrees was the dewpoint for a chamber that was fully sturated with water at 75degrees...anyone else on this?

tomatofarmer, the HI means its higher than 95%, your hydro meter probly only reads to 95% and its letting you know that its high than it reads.

why the hell did you steal it? thats fucked up shit! thats bad karma! i bet you steal your family their christmas presents! lol

>>>>>>>>>>>>>>>>>>>>casings provide alot of thier own humidity>>>>>>>>>>>>Yes they provide alot of moisture, but its stillk essential to have 95% humdity in the air for pinning....how often do you spray the walls? What if my chamber doesnt seal 100%? Will i have to spray 50 times a day? Does anyone else do this wall spraying? Ill need to hear more and maybe Ill give it a try on next weeks batch, thanks

if you take a fruiting container with 75% humidity with a temp of 75 inside. Drop the outside temp you will get lots of condensation but the humiidity will still be around 75%

Thats what Im talking about, its 70degrees outside of the terrarium and theres no condensation.....I put the chamber on the ground where the temp is 1-2 degrees cooler and I see condensation....very small margin, very misleading and confusing because I have 2 terrariums in the exact same room and the one higher up gets no condensation, where the one (2 feet lower) gets a bad breeze I gues and condensates....:|...

yes, i know 95% is needed for pinning. i spray my terrarium 2-3times a day or when the walls look dry, but i dont use perlite in my casing chamber, thats why i spray as often as i do. this way it is much easier to regulate when it comes time to drop the humidity. and im sure lots of peopl spray there terrarium, why would you question this?

Well this is my very first time growing mushrooms and I understood spraying and fanning twice a day was with a perlite setup, but obviously it wasnt so Ill take that question back. Yes, it seems much more practical to do that, that way its less of a hassle to kepp the RH at 85 later on. Isnt it a balancing act with having to spray when it come to fruiting? I mean, when you spray, right away the humidity will go up, but I know with my rubbermaid that isnt airtight, the humidity will drop right away and ill constantly have to keep an eye on it....I find if I have perlite maybe I can find a way for all that water to evaporate at the right speed constantly by poking holes in the chamber and covering them with filter disks. When I need more humidity I can cover the disks with tape on the outside...some peeps leave the lid a bit open but id be paranoid about some dust getting or bacteria....angryshroom said he just empties half the perlite out of the chamber and leave an aquarium bubbler goin, but dumping out that perlite would be a hassle, removing the casings then cleaning up and all that shit................any teks out there anybody that works with perlite to get the Rh to 85%????

Mine was a franklin something of another from radioshack.com that had indoor/outdoor min/max temp/humidity. I stand by the "it sucks" statement, but maybe I just got one from a bad lot or something.

Edit: Mine was an Oregon Scientific Model No. EM-913R (made in china) and I would not recommend it to anybody for cultivation use. It was an indoors/outdoors model that has the wire sensor. I did not use the outdoor sensor, but put the entire unit (minus the wire/outdoor sensor) into the grow chamber. The unit would max out around 97% on the humidity reading and the entire thing would "lock up". The temperature/humidity readings would not change... even if I stuck it in the fridge... I had to pull the battery to get it to reset. It would also "leak" allowing condensation to form between the LCD display and the plastic face cover.

radio shack has many hyrgrometers. The one you want to get is the unit that is meant to be able to go outdoor all by itself. Not one of those indoor/outdoor units that have that wire on them that read temperature.
All that wire reads is temp and it has nothing to do with humidity.
They have units that you can put outside all by themselves with no wire. This unit is actually meant as a remote controlled unit for and indoor unit so as that you indoor unit can get the outside measurements without a wire.

The best unit I have found is from Radio Shack. Part #63-1031. It is actually a remote sensor for another unit but it also works as a stand alone unit. It is designed to be used outdoors and as such works quite well for our needs. You do not need the main unit unless for some reason you want to be able to take readings from another room.
