Grow Indoor Plants in Water: The Complete Houseplant Hydroponic Gardening Guide
(deepgreenpermaculture.com)
"Indoor plants not only add a touch of greenery to your living space but also purify the air and boost your mood. While traditional soil-based planting is popular, growing plants in water, known as hydroponics, is gaining traction due to its simplicity and aesthetic appeal. 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."
This likely won't work well long term.
Roots need a lot of oxygen, and as the author already stated, the water can get stale quickly. In my opinion, changing the nutrient solution "every few weeks" is nearly not enough. For pothos and the others mentioned this might work for some time, but even there, aeration is needed.
Another problem is algae growth. I tried using transparent glass bottles a while ago, and after just a few days, the whole bottle and roots were coated in green sludge, killing the plant.
There are a few great solutions for those problems. You absolutely can (and maybe even should) use hydroponic systems indoors.
My two favourite ones for that are Kratky and expended clay bubbles. Both are really great!
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 🙃
