This tub is a part of my RBI Iris sweaterbox rack. I worked my way up from 1 row, 2 rows, and now 3 rows. The humidity is still 80%. I have not even tried it with the water bowl yet. If I put any more holes will this affect the temperature gradient negatively? Especially in the Winter?
Before anyone asks, the substrate is 75% aspen, 25% eco earth. I let the eco earth dry for two days, so it's not wet. The mixture is definitely a bit more humid than 100% aspen but should the tub still be this humid with as many holes as it has?
If someone with racks could please show me pictures of their tubs it would be great. I could it use as reference.
