re: Is the generic version of Certainty, Sertay, just as good?

Gotcha. I had sod pieces rooting down (not fully) by day 3-4 after being laid. I did utilize 13-13-13, hydretain, and some granular soil compost / biochar and have watered the hell out of it the past week. I really think it could be ready to mow in the next 2 weeks or sooner, but was wondering about how or if to treat the weeds as well.

Appreciate the help!
