First time owner - How is my setup?

Here is another thought. You can always place a smaller tub enclosure inside an un-divided T8, use the full sized RHP, and just place the tub where it gets an appropriate gradient. (Obviously some experimenting needed) ...

This may only be needed for a few months and would be cheap. The RHP would do a good job heating it and save you from having to spend extra on heat equipment.

I've done this with a new BP before to good success.

Now that is a great idea! I may steal that one myself.
