Yes, all pvc enclosures and racks here. I only use heat tape/uth in my racks. All the larger enclosures are heated with RHP. Bob definitely knows his stuff and that's the size RHP I'd have guessed he recommended.
The only enclosures of mine heated with RHP and with a floor hot spot of ~87 are 12" tall. Everything else is 18-24" tall and none of the RHPs ranging from 80-190 watts will get the floor to 90 degrees without turning the enclosure into an oven.
If you adamantly need the floor hide on warm side to be 90 degrees you'll need a UTH/Heat Tape under the enclosure with thermostat probe between the heat and the enclosure (re: link I posted).
Here's a link to some enclosures I built up a while back. All of them heated with RHP on herpstat thermostats. The shelf and perches under the heat panel are the only places in the enclosure that reach 87-90 basking temps. Everywhere else is cooler. https://ball-pythons.net/forums/show...nd-Accessories
Most of my animals are semi arboreal and are very proactive about choosing their preferred temp in the enclosures. There's certainly nothing wrong with giving a ball python a 24" tall enclosure, but it requires some additional work and hardware if you're dead set on having a floor temp of 90 degrees in the hide.
