Our retention pond in our neighborhood has a lot of algae and problematic plant growth due to the surrounding farms and lawn runoff, so we're experimenting with a floating island to pull nutrients out before they can cause problems. This will also provide some interesting flowering plants, and more fish habitats.
Will be an interesting experiment to see what survives and what does poorly.
Zinnias, sunflowers, marigolds, and a few others are in net pots, inserted into cutouts in EVA foam mats.

You conveniently left out the part where I said to show me the research, and I'd read it.
So far I've gotten a single link to a single paper that was irrelevant to this project, and a whole lot of "you're doing it wrong, trust me bro" from two people.
The part that is basic plant botany and anyone with a basic understanding of how a plant grows would know…? Plants absorb stuff from the soil and hold it, some are better than others. The same has to be true for other mediums like water and coco….
You’re arguing that neither of those are true claims….
