OK,
I am all excited. Today I am in the process of setting up my first rack.
I bought it used from the guy I got my male Pastel from. It is a six tub with a Ranco theromostat.
Right now, I am letting it get up to temp and then will add a tub to get the inside temp adjusted.
I got this a few months ago but was waiting for my new Balls to get done with quarrantine.
I love the search feature on the forum. I was going to post for help programing the t-stat but found the info in a search.

Just wanted to share
