Using HovaBator 2362. Can anyone tell me if I need to worry that the level of water in the 2 troughs has gone down to about half of what it was since we set them on day 18? It's 98-100 degrees. Been following things by the book, except candling - didn't know what we were looking for since we're first-timers. There are no pips or cracks yet, and we're nervous that if it takes another 24-36 hours, there won't be enough humidity.
