Humidity question

[mstricer]

Did u calbrate your hydrometer. 50% ins't to high unless you want to do a dry incubation. Mine was like that the whole hatch and I had 100% hatch. Follow the directions to ur incubator.

Thank you for all of the replies, maybe there is something wrong with my hydrometer. The temp is a steady 99.5 F and the humidity is still steady at 52% after 4 days. I would like to be able to set the eggs tomorrow. Does anyone know of any tests I can perform to see if it is in fact the hydrometer? I only have one and would prefer not to wait to get another one...
I am thinking it is probably correct as we live in a log house and it is snowing outside however this worries me that the humidity may go down as the weather clears up. Any suggestions? Should I put water in? Is dry air incubating different from regular? Sorry- I have never had this problem before.
By the way I am using the brinsea octagon 20

there is a way to calibrate the hygrometer takes 24 hours. I don't know off hand but search for "calibrate hygrometer" you should find what I'm talking about.

Thank you. I found one that I will try

Don't put water in just yet. Only when you notice that the humidity went down. Good luck with your hygrometer!

Calibrate your hygrometer. Only takes about 8 hrs to do. Will show you how far off it is.

Only way to get 52% RH in a dry incubator is if the humidity in the room is higher than 52%. Or you have a room temp of 99 degrees and have 52 % humidity in the room.

The incubator will pull in room air through the vents... (they are open right?). It will then heat the air up to incubator temp... 99.5 degrees (or thereabouts). When you heat air, it's relative humidity will go DOWN. So to end up with 52% RH in the bator, the room RH % would have to be higher... since I'm guessing your room isn't 99 degrees.

For instance, my incubator is kept in my temp and humidity stable basement. Temp is 55-57 degrees and RH % is right around 50% all the time. My dry incubator relative humidity is around 27% (hygrometer calibrated).

Be aware that room RH% will fluctuate with outside temperatures... and with warm/cold fronts coming through. So you need to have the ability to add water should the humidity drop.

That said... I would not worry about incubating the whole 21 days at 50% RH. Many have done it, especially when staggering hatches. I'd candle the eggs at day 10 and 18 to ensure the air sac is looking the right size. Air sac too big... increase humidity. Air sac too small... decrease humidity.

Good luck!

So I have previously posted that the humidity in my incubator right now is a little funky. I have not had it plugged in without any water in it for the last 4 days. The temerature has not given me any problems but the humidity is a constant 52% w/o water. I have been told that, while slightly high, should not give me any problems with my hatch. To be sure that my hygrometer was correct I have callibrated it which showed that it is high by 3%. This would put my humidity at 49%. Is this still potentially too high?

Wanted to ask if with a temp of 99.5 to 100.00 degrees and a humidity of 50% should i open the other vent on my LG... forced air fan installed.... haven't put eggs in yet as still making sure everything is right... just bought the hygrometer today.. do have water in mine... all water trays are full....

no need to get nasty about it.. mods ??

How was that nasty? I see nothing wrong with what was said myself.

he/she thought you meant are your vents open? as in your rear end...pretty immature lol

I am having the same exact issue! I am getting a high reading even without any water at all. Even after I calibrated both of my hydrometers. I just added a tiny bit of water for safe measure. Right now my humidity is measuring 53% with one and 64% with the other. It is very frustrating as I don't know which one to go by...
