Great information right there! @DankwingDuck
Now i understand what you mean with the roots, that doesn't look good at all. 🤢
Reading thru your post I feel more and more sure and proud of how healty my roots seems to be for being my first grow in a custom made RDWC. No odor, no slime, clear water, pleasant earthy smell.
The only thing I use for my roots in my system is Ultra Enzyme:
"Enzymes are natural process catalysts. Gold Label Enzyme contains enzymes that break down dead root material into nutrients that will benefit your plants and make room for new root development. You can regard them as the cleaners and recyclers of your medium."
Do you reccomend that I start using H2O2 or beneficial bacteria? Maby there is no need since everything is going well?
My water have an average temperature of 22 degrees.
