Do you make holes in your rack tubs or not?

It really depends on the humidity where you are. This is something you have to figure out on your own with some experimentation.

Just remember to not put a load of holes in right away. You can always make more holes, but you can't take them away.


In my CB-70 racks, for example, the room humidity is anywhere between 25-35%. The tubs have 0 space from the top of the tub to the shelf. I have 7 rows of 24 holes and the humidity inside the tubs are about 70%.

However, in my hatchling rack 6qt, there's 4 rows of 24 holes and the humidity is about 60%.
