Mold on stem/foam collar? DWC

[letsgro]

Noticed this white fuzzy-looking mold on two plants yesterday. Not much change overnight but I am going to change these 2" collars out for clean larger ones to help support the plants.

Any suggestions for treating the mold before putting clean collars on?

I have used a cotton swab and distilled vinegar to kill mold before. I would make sure you have alot of air movement to keep it from coming back.

I’ll see what I can find on distilled vinegar. I figured maybe h202 as an alternative.

I have adequate air movement above the canopy, enough that leaves and branches are slightly moving. However, the bucket system I have has drain lines too high and the water level was saturating the collar occasionally.
