Are your buckets and reservoirs completely opaque, preferably black?
Other bacteria can appear greenish and some forms like cyanobacteria also use photosynthesis and can appear green.
What are your water conditions like (ph, ppm at the source, ppm after nutes are added etc....)? What are your water temperatures?
Recently I've bought a DWC.
I already have all materials, just a few questions.
After a few troubles with my roots, water, ... i'm stuck. I can't seem to find what the actual problem is.
I was wondering if you could explain how to start a DWC from scratch. Like, what are the steps for a perfect start-up?
I use tapwater (in a container of 50l) which has Ph 7.4 so that is obviously to high. So I add Ph-down till it's 5,5 - 6 Ph.
After adding the airstones, how long should it be bubbling?
When do I add the nutrients?
The seedling is put in rockwool.
After a few days checking it has a few roots which already show rootrot, fungus, ... even when there is no lightleak. (checked and confirmed!)
The few roots that are visible touch the water slightly, so adding plagron pure zym and Plagron Hydro a&b. After 24h I have like a "foamy" texture on the sides of my bucket, where the waterlevel is. Is that normal?
As i mentioned, I have everything to start a DWC. I just need to know how to start from an empty bucket, a seedling in rockwool and when to add nutrients.
