I am thinking of buying that mixing tub too. That will come really handy for big batches of mixing. I have so many that my mix is usually just mulch, potting mix and perlite. As usual I am behind my repotting, the goal for repotting is so the pots are not clogged by roots. That's usually the cause of my issues when it is rainy season. Since my pots are shallow, the roots sometimes are on the media that stays wet most of the time.
