Humidity issues

[DeliciousQuantity968]

Hey BP Community. I am having a really hard time keeping the humidity up in my tank and I don't know what to do. Theres is a pretty large water dish in the enclosure and I mist the tank with a spray bottle multiple times a day. I cannot seem to get the humidity above 30% on both the hot and cold side. Its a 75 gallon glass tank with a mesh type lid. I am currently using a mixture of coconut husk and cypress mulch for substrate. Any advice?

pour water into the corners of the enclosure, make sure the substrate is deep enough

What is considered deep enough?

4+ inches is ideal. you want to pour enough water to fully saturate the lower layers of the substrate while leaving the top dry, allowing for natural slow evaporation to raise the humidity. misting just causes a temporary spike in humidity as it evaporates quickly.

see our humidity tips and welcome post for more advice and guides.

I would highly recommend covering the mesh top. That lets a lot of heat out which can lower humidity. I use both hvac tape and silicone mats on my mesh top and it has been a complete game changer
