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 !
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.
