Hydroponic succulent growing?

I got these glass baubles as a present and while I'm not really into decorative stuff, they do look nice and tempt me to experiment with hydroponics.

Do you think it would work? The plan is to fill the baubles with gravel and stick a cutting or so in to root and live. Best candidates are Senecio Rowleyanus or Senecio Curio Articulatus (thank you @Michael Hewett )

Should I add a spoonful of compost or just go fully soilless?

 

I have zero experience with hydroponics, but succulents don't strike me as suitable candidates.
In addition, if it worked, you would need to add some nutrients to the water and this would cause algae to have a party, and you continually cleaning the baubles.

 

My experience with succulents is that they don't like standing in water/soggy soil. I don't know what to say really, but you could try and see how it goes.
I've never had any success with Senecio rowleyanus. I have grown Curio articulatus for many years though, but I don't know how it would do in water. I always keep it on the dry side. All I can say is try it and see how it goes.

As for gravel, well, if you only use that you'll have to give the plants a feed sometimes. Gravel has no nutritional value on its own. I know succulents like poor gravelly soil but they do need some nutrition.

I would try it and think of it as an experiment, you don't know what the outcome will be but it will be interesting to find out
If it's a success then good for you, and if it isn't successful, at least you will have discovered something won't you .

 

Id be more inclined to try air plants.
No standing in water though.

 

Hmmm... I'll give it a try. At least it's something new, and if it turns out to be some rotten plants in pea soup and broken glass, it will

Google gives me some tips, interesting: Growing Succulents Hydroponically - a Full Guide | Gardening Tips

Thanks!

 

That was interesting.

 

Update nearly a month later- so far so good.

I thought I made a blooper by filling the Curio bauble up too much so that the stem has been sitting in water rather than just touching- but the cutting is still plump and is in fact growing an aerial root



The Rowleyanus is also still plump and the upright cutting I plopped in as an indicator is still firmly erect. No sign of any roots yet though.

If they start to grow roots I'll start feeding them but at the moment I'll just let them be.

 

Very interesting @Selleri! Do keep us updated to how your experiment works!

 

Update 9 months later:

Both experiments are alive and have some new growth. They probably would have more new growth if I hadn't totally forgotten about fertiliser That's sort of the basic stuff when playing with hydroponics but hey ho, at least they have not turned into swampy pea soup



Rowleyanus is hosting a tiny growth of moss in the opening which looks quite nice.
