Thank you for all the responses! I am also using sterilite bins. This is my design, I'm going to play around with side ventilation tonight.

I noticed you've built feed columns in your bins. How do you find they work? ATM I just put the food in the cored on the bedding lol.
I was looking at the dimensions of the concrete mixing pans and they appear to be similar in quart capacity but there's more floor space in the pans as they are more shallow. Should I just stick with the 65 qt bins and keep my groups to 1.3? Maybe make some bigger bins for grow outs?
Thanks guys/
