The problem of eggs that do not hatch, despite their fertilization, met by breeders gave me the idea of this subject.
The importance of the moisture content during the development of the egg and hatching in our breeding rooms pushes us to find solutions to regulate it, especially during dry periods.
Previously I used an ultrasonic humidifier :
Adjustable and ideal, humidifier and ionizer at a time. However, after a year and a half of use, he is now making his own by having untimely stops. So I opted for a much cheaper solution: Saturation ceramic (about 5 euros per unit in DIY stores) :
For my part I monitor daily hydrometry and set myself a minimum of 55% moisture in the air.
Below this moisture content, I put the saturators on the oil-filled radiator (which dries less air than the electric radiators type radiant or commonly called "Toaster").
The principle of evaporation caused by the heat of the radiator works well, but it takes about a day to see the effects.
If I see that the humidity does not rise enough, I cut the air extractor or regulates it. The air extractor is connected to an extractor speed controller socket.
