The incubator i made is a styrofoam box, i ve put a heat man inside, then a big recipient with water,
then the shoe box with eggs in the recipient, in a way that it doesn't touch the water.
Eggs are on wet vermiculite, i could not find a plastic grid.
Humidity is now 76% and 31.8 on the humidity/thermometer and 31.9 on the stat.
When i was testing the incubator i used just water (substrateless) and a box with drilled holes over it, and i had 100% humidity, but i don't feel confident with eggs on a hard surface, condentation on the bottom of the eggs, so i used vermiculite...
