DWC Root Slime Cure aka How to Breed Beneficial Microbes

This root rot really is a bugger. I have brand new system (modular flood and drain) and my roots are black, no slime. I don't understand it I have kept my temps very low below 65f/18c. Flooded every 2 hours lights on and once during lights off. Roots were pure white before they went into the new system, has me beat.

I flood, let it sit for 2 minutes then drain. Flood height is about 2 inches from the top of the media.

I’ll try paying it forward since I’ve been neck deep in literature and forum posts on this topic for the last month.
  • what nutrients are you using?
  • Is your reservoir well aerated w/ air stones and/or waterfalls
  • How low are your temps? Apparently too low during lights off can invite mold (which could be the black stuff)
  • Are you using any additives aside from basic nutrients?
  • Is your reservoir completely light proof?
  • Are you ensuring your hands and tools are super clean before touching anything?
  • What substrate are you using?

  • what nutrients are you using? Botanicare Kind-Tea-Silica
  • Is your reservoir well aerated w/ air stones and/or waterfalls Waterfall 200 litre res
  • How low are your temps? Apparently too low during lights off can invite mold (which could be the black stuff) Mmm quite low as low as low as 14/57 on some occasions
  • Are you using any additives aside from basic nutrients? Botanicare Tea-Silica- Yellow bottle Roots (until week 3)- Photosynthesis Plus
  • Is your reservoir completely light proof? Yes
  • Are you ensuring your hands and tools are super clean before touching anything? I don't wash them more than usual.
  • What substrate are you using? They are started in a small pot of 60/40 maybe a litre, then potted up into clay balls 6.5 litre Aquapot
 
The original small pot - what medium? I used peat plugs for a DWC setup and it introduced algae almost off the bat because the peat doesn’t drain.
Think about maintaining a more stable temp at night.

What is your source water? Tap, well, RO? what ppm? That's way too much flooding at these temps. I flood just at lights on, then every 4 hours then just when lights shuts and keep it 12 hours without flooding while lights are off. I do that with temps higher than yours. You don't want the roots saturated all of the time. You might want to run some H2O2 or poolshock periodically to help them recover.

hi i have a full starter kit from biotabs and voodoo juice and rhizotonic, can i make this tea out of it? The biotabs in the set have mycorrhiza, bacteria and here I'm not sure but I think there is also something to feed the microbes because it resembles caramel, I also have voodoo juice which has a bacterial strain and rhizotonic or vitamins ... will I do something about it for DWC?
