In this guide, we’ll explore which indoor plants can be grown in water, how to care for them, and other useful tips for successful hydroponic gardening."
Thanks for your input! That is super good to know. I won't try their suggestion haha
You can, if you want. Just do it with some spare plants, ideally from cuttings.
You can pour a few drops of hydrogen peroxide every few days into the jar, that will supply them with oxygen.
Or, you can go with Kratky bottles if you want the "plants in water"-look :)
I can share a few pictures if you're interested 🙃
