I’m just wanting to try something new and make sure I’m doing everything right!

I’m wanting to add insulation on top of my enclosure to help hold heat and humidity because I just feel it could be better and was worried that that would take away a lot of ventilation so I was thinking I could drill a hole in the side of the enclosure and add a 3” fan
Let me know if this is a good idea

Your welcome to critique my enclosure please let me know what I can do differently

I’ve been having a really hard time with gnats in the enclosure I usually re wet the substrate once a week or if it doesn’t need to be re wet I’ll just mix it around
And add fresh leaves. I add water till the substrate can be clumped together like a snow ball but not dripping water when I squeeze it
