This lid modification is for folks using Hovabator or any top-heated incubator. Its a necessary modification in orddr to build enough condensation and to raise humidity levels. Leopard gecko breeders using Hovabator remarked how the SIM wasn't building enough humidity and eggs were denting. When the sponge is attached to the lid and dampened, the heat above allows condensation to build up on the side walls thus keeping eggs from drying out and denting.

The substrate below the grid can remain Vermiculite, perlite or what ever medium you use. We are testing the cellulose sponge here at Squamata Concepts.

For customers who have purchased the SIM and are using the Hovabator you can copy from the photos or just ask and we will send the parts needed to complete the modification.

Basically, its cellulose sponge attached to the lid using Nylon screws. Total cost for all of these is less than $2.50. 

Of course it could. Can I ask what kind of incubator you are using?

I have a pair of unsexed golden geckos.  I know they're egg gluers.

One of the goldies laid and egg inside her(I'm assuming) coco hut on the paper towel substrate.

I'm wondering-if I tear the paper towel around the egg, does anyone think it'llactually hatch if I put it in the SIM???

As I said-I have no idea od the genders here...could be a pair or two females.

They're nippy and flighty, so I ain't grabbing them and looking at their crotches...

Anyone with any xperience in Goldies??

Here's her data:

I currently have a couple of V. glauerti (Kimberely Rock Monitor) eggs in the S.I.M. Instead of measuring out equal parts  perlite and water by weight, I added water to the mix based on conditions inside the container in order to build a light mist of condensation on the side walls. There's a mist on the ceiling of the lid but not enough to form droplets. 

I am getting feedback from breeders who are using straight water in the reservoir of the S.I.M. This creates a heavy condensation build up and many reptile eggs cannot handle this much humidity. Best results have been with water mixed with substrate, and container conditions stabilized and monitored before putting eggs inside. 

Below are my SIM inside a custom incubator. The top 2 are showing less condensation build up- these containers are being used for ackie and kimberley rock monitor eggs. The bottom 2 are empty but will be worked on until the conditions match the SIM containers above.
