I'm not so sure you need to "aerate" the soil so much. It dries out the soil more quickly, and it's hard enough to keep container plants watered as is. People put holes near the bottom of the bucket for drainage. If your buckets are white, they'll reflect more light and heat than if they are black. If you're worried about them getting too hot, put reflective material (like aluminum foil with the shiny side out) around the outside of the bucket.
