Humi-Shield Mat-Fits All Reptile Humidity Mat 2'x4' – Silicone Reptile Enclosure Cover for Sliding Door Terrariums, Fire Retardant Terrarium Top Cover for Humidity Retention

I have a PVC with screen top. I use https://a.co/d/03SWFeK2 This humidity mat on top. I cut out a circle for a Ceremic Heat Emmiter and a light bar for daytime/UVB I didnt properly seal the bottom so the corners leak if I pour water there, so I pour it along the middle and mix it through (this is my boop noodle interrupting that process)
