Hi All

I have a Brinsea mini ECO manual turn incubator and a Janoel 24 autoturn incubator.

Both are fan incubators.

The humidity in each is sitting between 42% and 45% in each one.

I understand that the ideal humidity is 50% up to day 18 and 55%-65% during hatch.

The water channels/containers are full in each.

How do I increase the humidity in these incubators?
 
In the jsnoel, add pieces of sponge in the bottom to increase surface area. You can fill the whole bottom with water until it runs out the overflow hole and accomplish the same thing. Surface area increases humidity. You might also try placing the incubator over a pan of water so the local humidity is higher.

Do not close the vents to increase humidity, the ventilation is critical!

Not familiar with the other.

Fwiw, I don't incubate at 50%, I do closer to 30% then up to around 60, but I do a lot of strange things.
 
I also use the Brinsea mini Eco. I would recommend using lower humidity for days 1-18. I've found 35% to be perfect. Do you have any room in the mini to add a sponge during lockdown. Are you in a very dry climate? I'm running my mini with NO water and I can't get it under 50%!
 
I too use a lower humidity aiming for 30-35% the first 17 days. I use 75% for lockdown because I am a meddler.

I wouldn't go above 40-45% for the first 17 days, and I would definitely candle at days 7/14/18 to make sure that your air cells are on target.
 
Hi again.

During the first attempt at hatching I filled the water containers and paid no real attention to the humidity, I just kept them topped up.

The eggs were mail order and I had 3 successful hatches out of 12.

This time I have bought a digital hygrometer and have been monitoring the humidity and its sitting pretty constantly at 41-42%

The temperature is spot on 37.5.

Am I worrying too much and should I just raise the humidity from day 18?

Personally I'd leave it alone for now and check the air cells at day 7. If they look to be on target, leave it if not adjust according to the air cell. The lower humidity is proven to benefit the styro bators and I've seen success in some of the plastics. @scflock uses a Brinsea, (albeit the bigger advanced) but finds 40% ish works better for him. Let your air cells guide you at least for the first hatch in a new bator then you'll have a better idea of what works.

I think I'll stop worrying for the first 18 days as the humidity is above 40%

Then at day 18? Panic! what do I do?

My usual answer for that is sponges, but with that mini it's so small. Is there anyway you could cut strips of sponges and stick in between the eggs. Wadded up wet paper towel or clothes help as well. You also can put a small humidifier in the room beside the bator and add humidity to the room. The ambient humidity does help the reletive humidity inside the bator.
