obviously, I am a proponent of ambient room heating. it's worked for me for a long time. equally obvious is that individual enclosure/rack heating has worked for a lot of people for a long time. for a host of reasons ambient room heating may not work or be a reasonable approach for many keepers. any change to husbandry, especially one as significant as this, should not be undertaken lightly. Josh did his homework on a couple of previous threads requesting feedback from those of us who use this approach and decided to give it a try. In his case, because he already had been using the more traditional methods, he is in a good position to fall back if necessary (don't get those geckos just yet Josh). not everything works for everyone, but I would encourage anyone thinking about this to give it a try. but you won't find me on a soapbox stating that it is better (no, no one is being accused of being on a soapbox!)
