Ok, read some posts on here about how to calibrate my hydrometer, but now I am not sure if I did it right. I put a small amount of salt and water into a ziploc bag until it made a paste. Then I put the hydrometer in the bag without getting it into the water or salt (it is electronic, and I did not wish to ruin it). I left it overnight. Is this correct? Or was I supposed to put it actually in the water and salt solution. According to this my reading was about 10% low (it read 65% after being in the bag overnight) I am leaning towards my calibration being correct, as even when I get my bator so moist that water droplets start forming in the top, it still reads at only about 75% I am also trying to figure out humidity rates for my incubator. Just read post after post about dry vs wet incubation and am still confused. I live in a very arrid climate, so normal humidity in the room is reading at about 25%. (which would be 35% if my calibration is right) Also am at a relatively high elevation. Do these two factors effect what humidity I should have in my bator??
