Algae / Mold on Smart Pot

Discussion in 'Sick Plants and Problems' started by Cmititi, Jun 27, 2017.

  1. Hey guys, just recently started noticing some green patches forming around the bottom of my smart pots. Can anyone identify the problem and provide a simple fix?
    Appreciate it greatly !

  3. Mine have the same, have you been able to figure out the cause?
  4. It's algae. On the outside of the pot it's no issue. When it gets on roots in DWC, or if it's clogging tubing, or blooming in a rez - then it's an issue. On the outside of the pot, it's just cosmetic and won't interfere with anything.

    Fixes are to use dark smart pots or block all light to that area - which in this case are probably not practical. Any sort of algaecide is also bound to be bad for cannabis as well.
