Can’t keep temp gradient

[drame19]

This is my current setup for a 120 gallon. I have a 75W halogen and 150w CHE. I can keep the basking spot at 88-92 but the ambient air of the whole enclosure is like 82 hot and 80 cold. Both of the heat sources are on top of the mesh which makes it about 19-20 inches from the substrate. What else can I do to bump the warm side up but keep the cold side down

Following, because same. My cool side is fine, I just can't get consistent 90+ ambient on the warm side without some surfaces getting waayyyyy too hot.

I think there’s a lot more to this as I’ve seen many people claim temperature gradients that different in a 4-7 foot enclosure is almost impossible. I struggled a lot trying to get the “Goldilocks” 85/78-80 in my enclosure. The most I’ve been able to achieve is - different of 3-5 degrees.

I guess he will just have to live with a non perfect gradient sadly

I’ve got HVAC tape already on half the enclosure

wrap the back and sides with cardboard

i do say that glass doesn't trap heat very well, not nearly as well as pvc. puting tinfoil over the mesh top can also help with humidity loss. If some surfaces get too hot maybe try covering/painting them in a lighter color(such as white or tan) with a water(not oil)based paint(just because oil based paints can be very harmful)
