I know that bacteria and mold has something to do with it. I grow marijuana using deep water culture, the plant sits in clay balls and the roots grow down into a bucket of water. Soil can grow bacterias and house insects, but by using a black bucket that doesn’t refract light then mold cant grow. I also put bubblers in the buckets to create movement, which also stops algae. Just to be clear, im an idiot, I dropped out of highschool and grow weed. Don’t take what i say as gospel.
