>>Florida must be nice I have to spend a fortune keeping the reptile room at 80' here in North Dakota during the winter.
Jeremy, what part of ND? I'm in Rapid City, South Dakota. Just moved here last May. We love it.
Drop an e-mail, I may be able to help you reduce your heating bills.
>>Chris uses rope light and I'll let him explain that.
I only use rope light because my racks are in a heated room and I only need to provide less than 10* of supplemental heat. I also need night-time temperature drops so shutting off the light source is no big deal.
I'll be glad to go into this in more detail if the original poster has decent ambient room temps.
>>>>Also off the topic, next time I build a rack what is the safest material to use and where can I get it, expanded PVC????...???
This is probably pretty safe for the DIY-er given it's anti-flame properties. It has not been tested extensively for offgassing but I understand it's generally considered safe.
Freshly cut sections of PVC pipe are often used around amphibians and delicate marine invertebrates so I believe the offgassing concern is minimal. These applications are not heated to the same degree as snake racks, though.
