20% humidity drop in 3 hours! WTF?
    #7567427 - 10/27/07 05:48 PM (16 years, 3 months ago)

Ok, so I checked my box at 3 o'clock the humidity was 90%. For some reason that is as high as I can get it. 3 hours later I looked again and my hygro read 70%. The only thing I did different was shut the door the closet that my fc is in. would this cause such a large drop in humidity? I am also wondering why I can't get over 90%.




I have about 5" of well drained perlite. This should give me plenty of humidity. Do I have too many cakes in the fc. Is it possible to have too many holes in the fc?

Did you calibrate your hygrometer?

Yeah. Its a brand new hygro and I did calibrate it. The two jars are just water with a bubble stone in it. I read here that people were using bubble stones to raise humidity. I didn't understand how but I figured I would give it a shot. I don't think there doing jack!

when it gets warmer humidity drops. the bubble stones are hooked up and running, and the perlite is wet? how often are you fanning it?

From what I read the bubble stones are just dropped into the jar. I know, it sounded dumb to me too but I was desperate and willing to try anything. I'm fanning them 2 or 3 times a day.

go to walmart get a small air pump in the fish area and some line; get a spliter to hook up both bubble stones and i'd use a coffee filter over the spliter to filter the air(the water wont filter the air) this should raise humidity and add more fresh air. also make sure you have 5" of perlite that should help your humidity. make sure you mist when you fan.

As temperature rises, relative humidity drops. There is still just as much moisture in the air, but the air can hold more at higher temperatures.

I see your thermometer and hygrometer on the side of the unit. Perhaps the hygrometer is hanging right over a hole, thus giving an artificially low reading.

Make sure the perlite was rinsed well, and then drained before placing in the terrarium. Rake your fingers through the perlite to fluff it up and leave an irregular surface. This exposes more of the perlite surface area to the air.

Calibrate by the method I've posted, not salt teks.

A coffee filter won't filter the air either. When it's used on a jar, it's merely a dust cover. Regardless, you don't need to filter air going in to a fruit chamber, as a fruiting chamber doesn't need to be sterile. The mycelium should be well established and able to ward of contams on its own at this point.
