Hey guys, I'm putting this here as I couldn't find much on it. I've gathered most the materials I need to use to make a snake rack and just need to know size details on the tubs before cutting materials. What size bins should I use for adults. I've never bought bins before where I had to worry about how many quarts or such the bin was, so I'm not sure what sizes they are unless in store and looking at them. And also, does it.matter what type of bin I use plastic wise? I've never used heattape on a rack before, so being safe is a priority for me. And yes I have thermostats. Thank you
