Hey guys, just noticed this post. Sorry for the late reply.
I'll say what Bill regarding this being just my experience. I live in Central Florida where the springs, summers and even most of fall are hot and humid. Generally, when I get new hatchlings I keep them inside in a melamine rack unit that has a heat tape. The warm end is around 84 degrees and the cool end is much cooler as I keep my house pretty cool (71 at night, 77 max during day, rare though). This is how I keep all my baby snakes, TPR's and graybands, as well as getula kings, corns, etc. Seems to work fine.
Once they are big enough to be moved to larger cages, they move to my garage. Again, I live in Florida. the cages are well-ventilated, the garage has a window that mostly stays open and I have a lot of oak trees in my yard that provide some shade. But it still gets hot and humid. The hottest I've seen it is probably 93. And then only for a short time. but it does regularly stay in the high 80's to about 90 quite a bit. And of course, it's humid. All my snakes seem fine in this setup as far as feeding is concerned. None of my subocs has EVER regurgitated. I keep water in with them at all times but in small bowls. My alterna do great, one pair double clutch each year without any "coaxing" on my part. Again, feeding is not a problem.
Now as for breeding the subocs, I had several years of infertile eggs from large adults until Dusty mentioned that a lot of suboc breeders don't keep their males on heat tapes after brumation. that got me thinking about how hot it gets in the garage, especially since they are late breeders. By the time they get around to breeding they had been subjected to a few months of high temps. This year I brought my big male blonde inside. I kept him in the air conditioning with no supplemental heat. Again, house down to 71/70 at night, average of 76 during day. He ate, no problem. He also bred and for the first time ever fathered two clutches (one of 16 eggs, no slugs, 100% hatch rate). The second breeding was sort of an afterthought and occurred after I moved him back to the garage. That female laid 7 eggs, only one of which hatched.
So, in conclusion, I have had no problems KEEPING TPR's in hot, humid conditions. But have had problems getting fertile eggs. They'll bred, but lay slugs. I plan on doing the same thing this year with them.
Whenever I read articles about TPR's that suggest keeping them at low humidity and/no water and low temps I always wonder why mine have done great for me under opposite conditions.
Sorry about the long post Happy Thanksgiving everyone.
