RBI rack holes?

[RetiredJedi]

Hey guys, just bought a 4 drawer sweater box rack from Rich at RBI today at the white plains expo. Ill be setting it up tmrw but seems like a really solid product so far. It was good to finally put a face to the name!
Anyways, i was wondering where and how many holes you guys put in the tubs? I was thinking 4 holes up higher in the back and 4 holes lower down in the front. To draw in cool air, itll heat up and rise, and go out the higher up holes in the back. Is that wrong/stupid lol? Im trying to remember lessons from my physics class!!!
All advice is appreciated!

Mike, I have the same rack from RBI. I started my holes the same way you did, four high in the back and four low in the front. I think you find out that each tub is going to take a different amount of holes. My top tub has a lot of holes and the bottom one doesn't have nearly as many. I guess what I'm saying it's going to trial and error with them. I put about four holes each time until they got right. I would wait about an hour or two and check the humidity again before I added more if needed.
