I know there are lots of post on this, but i want to put out my situation. I live in wasington state and it gets pretty cold here. I'm expecting my first three ball pythons soon and i want to make sure the setup will be good enough. I am using a economy plastics four shelf rack with a herpstat 1. I bought some sterilite tubs for it but im not sure how many holes i will need for humidity. If there is anyone here that uses the same rack that can tell me what they did it would be great. The EP racks are pretty open and as i said it gets pretty cold here. I want them to be as comfortable as possible! Please give me any advice on your experiences.

If anyone needs pictures of my setup or anual weather numbers for where i live, just ask away.
