Need some help with the right humidity in tubs

Alright I have had my rack setup for 4 days now temps have been great 84 a night with around 50 humidity. During the day the temps are 88-91 with humidity levels from 60-77.

I keep freaking out when it gets to 77 is that to high for the snakes or should I possible drill a couple more holes in the tubs? Because it happens every day I have been writing everything down as far as if I set my thermostat on this temp I receive this result.

thanks as always guy

Maybe try poking a few more holes In your tubs. My humidity bounces around, darn snakes tip the water or the news paper substrate ends up in the water dish and sucks up all the water causing the humidity to escalate.

yah that happens to alot lol. I dont get to mad maintaining a tub I cant even explain how easy it is. I'm just trying to get the temps and humidity right
