Hi all,
I'm going to guess hydroponically in diluted waste water. How much the roots accumulated in terms of heavy metals etc. would depend on the waste, but if it was diluted pig slurry, for example, they may have picked up a lot of copper (Cu) etc.
I'd probably give it a miss, but that possibly is over-cautious.
cheers Darrel
It is, a quick search for "Vetiveria zizanioides" and "phytoremediation" on <"Google Scholar would pull up lots of papers">. One reason it has been used is that it is "luxury absorber" and <"can be used for phyto-extraction">.Vetiver grass is used in some places to help remove pollutants and excess nutrients in water treatment
That would be a little bit open to question, it would really depend on how the plant was grown.so I'm assuming these dried roots would be aquarium safe.
