Good day,  I would like to know what the medium is called that you "plant" the plants in when using a hydro-ponic system, and where can I buy it in SA?

Bunnings....
Either Peat blocks, coco fibre blocks, perlite or these pebbles for hydro plants.
You can also use a mix of any of the above.
The "pebbles" are usually out in the garden center.

You're welcome!
Before you buy check what is available and what suits your plants!
Peat moss for example is more for stuff like orchids.
The peat blocks are good for everything after a good soak and wash with fresh water bt only good for vegetables if you keep the material moist.
Perlite is mostly used to get more air and better drainage.
Most important thing if you go full hydro is to get a soil testing kit.
You want to make sure that the PH level is right and depending on the type of fertilizer that you don't get a build up of by products or salts.
Although if the hydro mix was really good to get your plants started a good flush with lots of clean water will balance most things out without the need of testing kits.
Can't recommend it for sensitve plants though or those that prefer only slight moisture levels.
