Do I intervene orthe wait some more

I am on 84 to 88 ambient only and it works for me so in theory you are correct. If the OP boosts to 84 the hot spot is no longer needed. I was just really curious about the the drop temp suggestion since it goes counter to how I have always thought. I suspect there is possible truth in what Albert said. Immature thermo regulation. And maybe some truth in the same vein with spider as Deborah suggested where their thermoregulation is possibly quirky. Something for me to think about since I will have quite a few spiders hatching next month.

Ok, I thought I was on the right track but was thinking 83-84 might be about as low as the ambient room temps should be. And I also believed that you were one of the people I knew of and respected that uses ambient temps in a temp controlled room. Thanks!

...and yeah, Albert and Deborah are two of the members on this forum I have learned a lot from and have a huge amount of respect for. I always pay extra attention when they post.
