What is you ventilation like? I test mine by using a paper substrate and keeping the RH at 60% than removing the water bowl and timing how long it take to drop to room RH. I don't like seeing over one hour. Most of mine change in 20 min of less.
Thank you. I had previously read the post you linked and wasnt sure exactly how to test ventilation. I will test ventilation in a little bit. I do have vent holes in my tubs but just a few. after testing I will add more if necessary. My 41qt racks also have a 1\8 inch gap between the shelf and top of tub. hatchling tubs fit snug but havent seen any issues within the hatchlings ever.
