I have two tents going off one 20 gallon humidifier with a big air pump and 2 foggers going 24/7. I can see fog flooding the tent at all times but the Rhizos seem to be wet. My casings failed so I scraped them off and induced fruiting. My Taylor Hygrometers read 87% RH Is this wrong or correct. I have taken them out of the tents and dried them out and replaced them with the same results. Any ideas as to how to the RH up to 99%. I have 12 12qt tubs with around 10 grams for a first flush. Its pitiful.

Mentioned this in a PM already but to restate it for the archives.
Digital hygrometers fail for three primary reasons... 1. They are intrinsically inaccurate above 95% RH by way of the means in which the sensor works. 2. After several flushes, even if you harvest before the veils break, the sensor will become clogged with spores and other debris and because you cannot access the sensor to clean it, it will become more and more inaccurate as time passes. 3. The are only accurate when their battery is supplying full power. As the power drops the rate at which the device looses accuracy grows almost exponentially. This is not when it's "almost dead" it starts about a week after you put the batteries in the device.
--- The easiest and most accurate hygrometer is going to be a $5.00 analog hygrometer (with a calibration screw) from a cigar shoppe. To calibrate it simply get a dish towel wet, wring it out and place it into a tupperware container with a lid on it. Ideally a container that is only slightly larger than the wet towel and place the hygrometer on top of the towel with the lid on it.
Come back an hour later and regardless of what it's reading, calibrate it to read 99% RH and it will be dead accurate for a very long time...

casings don't require RH that high. You'll be fine with your RH as it is although i would bet your hygrometer needs calibration. If your casings are being soaked then you have too much moisture.
-------------------- To get really high is to forget yourself. And to forget yourself is to see everything else. And to see everything else is to become an understanding molecule in evolution, a conscious tool of the universe. And I think every human being should be a conscious tool of the universe. . . . -JG i really am glad you came back to us instead of taking the other path. *hug* -A_S (RIP your final words to me will never be forgotten)

generally most can't be calibrated. ur better of with a nice anologue one that u can calibrate.
I recently got a digi one with ext sensor. it seems to be fairly acurate just now but I have ntoiced that sometimes when I fae it doesn't show a drop in rh and other times it does.
on mine I can get to the sensor and clean it. but its still battery operated.
an anologue one will not cost that much.
ur rh is probably near 100% is ur casings are getting soaked.

they are getting wet. It has taken almost a week of the environment being the same before they started getting wet
