Thank you Zach, I'm definitely a lucky guy!
I'm in the same position you're in. And thats what stops me from having more tanks. I don't think I can push my luck and have her maintain multiple setups, especially since I'm only home for half the year.
She was very hesitant at first, so I had to set it up where water changes were pretty easy to do. If I were you, I would still setup the pothos or any other plant anyway to get them establish just in case they change their mind and you deploy you.
