I have a smart pot with what looks like white mold on the outside of the pot what should I flush with.
If it’s from water run off, it’s probably salt buildup. You you mind sharing a picture?
Not mold salt build up them are smart pots right i had same issue
So just flush good next flushand can i loke scrub with tooth brush lightly on outside of pot.
It won’t hurt your grow , don’t panic .
I have several of these and dirt and fertilizer residues show up. I go to laundry down the street and put them in on gentle. If you put them on reg wash they will stretch. Good luck, Mike
