Please tell me how your humidity works on your incubator... as in how do you get the humidity to go up...? Can you set it and it regulates itself to stay at that humidity setting... or do you add sponges or bowls of water...? I'm not very happy with Brinsea.... unless I can find out all others work the same as Brinsea... The highest I can get humidity is 62%....(keeping all vents completely closed) Now they have a place to set humidity to whatever you want...lets say 72%.....but it won't go to that, and unit tells you that you need the pump... which is another $130.00 (which you were not told nor suggested to buy in order for this unit to perform properly). So when you go to set the humidy.... after choosing 72%, your then informed you need the pump... Problem there is.....a person on internet bought the pump and said it made no difference...he still couldn't get humidity to rise above 60% ... Which made sense to me because the container that holds the water can only be filled so high.... you CANNOT get any more water in it....! You can set a sponge on top but that's it.! Seems to me that Brinsea... should of added two containers to hold water....? They are now telling me to add more sponges... Where....??? Now if I do that....the sponges will have to be placed on top of eggs, or down in the area you hatch.. There is no other place to put them...unless they are glued or taped to the walls... I had to add 2 pie tins of water in order to get the humidity up to 70% now that's placing a pie tin in the area of where you incubate your eggs on the turner!! which if you have eggs there, there would be no room for pie tins...lol I'm just not understanding all the trouble I'm having getting the humidity to go up to 70% after spending $900.00 ! My temperature in the room ranges from 65 to 77 degrees... it's usually about 70 in here... right this minute at 9am in the morning its 69 degrees.....in winter it will be about 65 degrees. Any suggestions or helpful hints will be greatly appreciated...!
