Yes there is daily maintenance checking but I am just at the stage where I am trying to finish the rack first and decide how many holes to put.

I find that even without spilling, when left overnight, the humidity without holes is at 85%. I know I can tape up holes if I put too many but I want to start with less as I don't want to have something with so much tape on it if possible.

How many holes do you suggest I try first?
