Tortstork recommends using a HovaBator 1602N to hatch your Instahatch egg. We use this exact incubator to incubate all our species of eggs, both turtles and tortoises.
The HovaBator 1602N series of egg incubators claims to be the “World’s Best Small Incubator.” This is our model of choice for incubating tortoise eggs. Temperature control is provided by an ultra reliable “wafer” style thermostat. Built-in humidity channels make it easy to add water for humidity control.
