I don't have a problem working my solution a little bit more these days, and if I can spend the time I want in the tents then I'll do a sterile to living flow week over week with solution swaps. Pearly white roots are as simple as keeping it sterile and understanding your nutrients.
I know folks use hydrogen peroxide but there are considerations there that I don't know if most are accounting for. I use HOCl if I have to cheat. Otherwise, keeping the solution proper temp and O2 sat and labs pretty much take care of the rest.
