Ok last night i changed out the substrate in all of my snakes tanks and now im having a slight issue with the bps temps. I put about 3 or 4 inches of cyprus mulch in the bottom of his tank and besides that the setup is the same. But the problem is on his hot side its only 84 and on the cool end its 78. THe humidity is at 46%. I got the cyprus mulch from a hardware store. Its the same thing that a very reputable breeder around my area uses and a huge bag of it is only 5 dollars. But now since i changed it last night my temps have been to low. Now i was having the same problem with the boas cages but their cages warmed up to where they need to be. Do you think i just need to allow the bps cage a little more time to warm up because its a bigger cage? Advice would be highly appreciated.
