I'm having the same problem with my LG. I can fill the troughs at the bottom but can't reach anything else through the vent holes. I have opened the viewing area once to grab a sponge and put it in the microwave. Temp only dropped one degree and and about the same for the humidity. The hot sponge brings both back up immediately. I have had to close one of the vent holes to keep humidity consistent, otherwise it slowly drops about 10% in a couple of hours

. After running a dry hatch for the first 18 days, this humidity part is difficult. I have been averaging about 60-65%. I hope thats good enough. I don't want to keep messing with it. Today is day 20 for me, so hopefully if everything goes well tomorrow the hatching chicks will help keep the humidity up. What day are you on dblea? I'm having trouble keeping track of what has happened to who on here
