Micropropagation for long term storage of genetics?

Hope everyone is having a wonderful day.

I am a medical caregiver in Illinois. Illinois law states that a person with a medical card can grow up to 5 plants that are more than 5 inches tall. (Which is as grey of an area that there ever has been, but I digress)

I have a background in mushroom cultivation and I am familiar with working in sterile conditions growing fungus cultures on agar plates and using test tubes / slants for long term storage of certain genetics/cultures.

Was wondering if the same thing was possible for cannabis, and sure enough after doing some googling I came across the topic of micropropagation of cannabis to separate the cultivar from any contams or viruses and for long term storage of certain genetics.

This all makes sense to me and is really intriguing, because now I can save genetics pre-flower, grow them out, keep the ones I like and ditch the rest all while staying under the "5 inch" rule while at the same time not having to keep a 5 inch tall clone which would count against my total plant count.

Does anyone here have any experience in this practice?

I would really be interested in an advanced discussion like this.

Pictures like this one I found on google are just amazing to me.
