What are your recommendations for the heating? What do you use on yours?

The heating situation is what I'm most concerened about. I've been doing research and I'm finding a lot of conflicting advice. I also looked on AP and they don't have any videos on how to set up heat in T8's or T3's. They use flexwatt heat tape on their rack videos, but I've been seeing a lot of people recommend not to use heat tape (including Lord Sorril above). That being said, some of the random instructional videos I have found are using the flexwatt heat tape haha. It gets confusing on what is actually the right thing to do.

With the heating issues in my place looking to be dropping into the high 60's, would it be better to do the flexwatt heat tape, a UTH, or a RHP?

Also, any thermostat recommendations? The one I have is a basic on/off, but gets the job done. I'm not sure if something better would be required.

Sorry for all the questions, I just want to make sure I do it right the first time if I'm spending all the $.
