Long time ago (> 20 years already) I read an article about reproduction of plant material in "Agar Agar" culture material. The description was meant for home-experimenting.
So... no fancy stuff needed.
It was about growing potato plants from little chips of the root-sprouts.
I recall that the agar agar was to be mixed with the moisture that is inside a coconut. All made sterile by heating for a time.
The coconut material contains a lot of hormones and stuff, that regulate root-growth, bud-growth and shooting from the unspecialized cells that first grows to just a clump of cells.
I want to try with bamboo material, just for the fun of it.
If you know the details of this propagating method, please reply in the forum.
