Welcome to the forum, lots of knowledgeable folks here willing to share their experiences.
Just curious, any particular reason you've decided to go with TBH's? Personally, I've never tried them, but want to say I've heard they can be a little tougher to get going and have heard stories of beginners having limited success.
Not trying to discourage you in any way, just wondering what lead you there....
If you haven't learned already, most all aspects of beekeeping tend to be as much art as science and you will learn quickly, there are no shortage of differences of opinions on how "BEST" to do something.
My approach has been a willingness to listen to all advice offered and then make the decision that feels right for me and my bees.
